OBJECTIVE:To evaluate the methodological bias of systematic review and the reliability of counclusions of tradi-tional Chinese medicine (TCM) combined with transarterial chemoembolization in the treatment of primary liver cancer,and pro-vide evidence-based reference. METHODS:Retrieved from Cochrane Library,PubMed,Guideline,CBM,CJFD and Wanfang Da-tabase,high quality systematic review about TCM combined with transarterial chemoembolization in the treatment of primary liver cancer was collected for reevaluation. RESULTS:Totally 12 systematic review were involved. Results showed TCM combined with transarterial chemoembolization can improve tumor’s objective response,prolong the survival time of patients,improve life quali-ty,reduce postoperative adverse reactions with no serious adverse reactions reported related to TCM in the treatment of primary liv-er cancer. CONCLUSIONS:The clinical efficacy of TCM combined with transarterial chemoembolization is superior to transarterial chemoembolization alone in the treatment of primary liver cancer,with better safety.

Purpose:To explore the effect of anti-FasL on ADM resistance of K562/ADM cell subline and its possible mechanism.Methods:Control group,untreated with VER or anti-FasL ,VER-treated group,anti-FasL-treated group and anti-FasL +VER-treated group were set up. MTT、FCM、TUNEL、S-P immunechemistry and RT-PCR assay were used for detection.Results:Anti-FasL or VER treatment was capable of strengthening sensitivity of K562/ADM cells to ADM,ID 50 of anti-FasL and VER was 200ng/ml and 6?g/ml,respectively;DNA content of apoptosis from cycling analysis curve of K562/ADM cell was 7.42%,32.10%,49.29%,56.26%,respectively,and positive rate in situ apoptosis was 4.5%,36%,45%,58%,respectively,which represented a tendency of gradual increase. Anti-FasL was capable of effecting FasL and bcl-2 expression,but not Pgp.Conclusions:Anti-FasL alone or synergically with VER was capable of reversing ADM resistance of K562/ADM cell,which may be used as a novel reversor of multidrug resistance.

Objective To study the effect of gastrin on the proliferation and angiogenesis of human umbilical vascular endothelial (HUVE) cell in vitro.Methods The immunocytochemistry assay,realtime-PCR,and Western blot were used to detect the gastrin receptor (CCK-BR) expression in HUVE cells.After HUVE cells were treated with 10 and 100 nmol/L gastrin for 72 h,MTT and soft agar colony formation assay were used to test the cell proliferation rate and colony formation rate,and the vascular-like structures were observed by three-dimensional culture of HUVE cells.The half-ring and ring vascular numbers were counted with five random visions.The vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1a (HIF-1a) mRNA and protein levels in HUVE cells were detected by realtime PCR and ELISA assay respectively.Results HUVE cells expressed CCK-BR.After the treatment with 10 and 100 nmol/L gastrin,the cell proliferation rate was increased by 48.48％ and 82.82 ％ compared to the control group,and colony formation rate was increased to 31.33％ and 45.67 ％ as compared with 15.33％ in the control group(P＜0.01).Relative expression quantities of VEGF and HIF-1a genes were 2.3 and 4.6 folds (VEGF) and 20.76 and 26.77 folds (HIF-1 a) than those in the control group.The concentration of VEGF protein in culture medium was 221 and 392 μg/mg protein higher than that in control group.The numbers of half-ring and ring vascular structures were (14.00 ± 3.00,39.33 ± 7.57 and 34.33 ± 4.50)/vision and (8.33 ± 2.51,41.33 ± 5.85 and 37.67 ± 3.51)/vision in control,10 and 100 nmol/L gastrin-treated groups,respectively (P＜0.01).Conclusion Gastrin up-regulates the expression of VEGF and HIF-1a genes in HUVE cells and promotes cell proliferation and vascular-like structure formation of HUVE cells in vitro by being combined to CCK-BR,which may be involved in the development and metastasis of gastric cancer.

ObjectiveTo compare the therapeutic efficacy between warm needling and Western medication in treating chronic atrophic gastritis.MethodSixty patients were randomized into an observation group and a control group, 30 cases in each group. The observation group was intervened by warm needling, selecting Guanyuan (CV4), Qihai (CV6), Zusanli (ST36), Xuehai (SP10), and Geshu (BL17); The control group was by Western medication, including Omeprazole, Amoxillin, Metronidazole, etc. The clinical efficacies were compared after 8-week treatment. Besides, gastroscopewas ordered at outset and after 8-week treatment to compare the therapeutic efficacies.ResultIn comparing the clinical symptoms, the total effective rate was 93.3% in the observation group versus 70.0% in the control group (P<0.05); the gastroscope scores dropped significantly in both groups after 8-week treatment (P<0.05), and the score of the observation group was significantly lower than that of the control group (P<0.05). ConclusionAcupuncture-moxibustion can significantly improve the clinical symptoms and gastroscopic results in patients with chronic gastritis, and its therapeutic efficacy is superior to that of Western medication.

BACKGROUND:Currently, there are a lot of studies addressing oral microflora variation in patients wearing fixed orthodontic appliance. OBJECTIVE:To determine the changes in Streptococcus mutans, Lactobacil us and oral health in teenagers wearing metal orthodontic appliances. METHODS:Twenty-three who were subjected to fixed metal orthodontic appliances as testing group and 18 adolescent volunteers with no oral diseases served as controls. We col ected saliva samples from al the participants immediately, 90 days and 180 days after fixed metal orthodontic treatment to detect changes in Streptococcus mutans and Lactobacil us, which can lead to dental caries, and other oral parameters, including gingival index and oral hygiene index. RESULTS AND CONCLUSION:In the control group, there were no difference in Streptococcus mutans, Lactobacil us, gingival index and oral hygiene index at three time points. In the testing group, the hazard levels of Streptococcus mutans and Lactobacil us were significantly increased at 90 and 180 days than immediately after fixed metal orthodontic treatment (P<0.05), as wel as the gingival index at 90 days and oral hygiene index at 180 days became worse (P<0.05). At 180 days after fixed metal orthodontic treatment, the hazard levels of Streptococcus mutans and Lactobacil us, gingival index and oral hygiene index were severer in the testing group than the control group (P<0.05). These findings indicate that the fixed metal orthodontic appliance could lead to increasing of Streptococcus mutans and Lactobacil us, and reduce oral health status badly.

Objective To investigate the change of adiponectin level with menopause status in women aged 40 to 65, and its relationship with androgen. Methods A cross-sectional study included woman (aged from 40 to 65) who were in hospital for routine check-up at the Sun Yat-sen Memorial Hospital from August to October in 2013. All subjects underwent laboratory examinations of adiponectin, sex hormone binding globulin (SHBG), dehydroepiandrosterone-sulfate (DHEA-S), total testosterone (TT), collected anthropometric measurements and then calculated free androgen index (FAI) and body mass index (BMI). According to their menstrual status, the subjects were divided into 4 groups: premenopausal group with 119 subjects, perimenopausal group with 60 subjects, early postmenopausal group with 62 subjects, late postmenopausal group with 64 subjects. Results (1) Adiponectin levels declined to its lowest level in menopausal transition and gradually becoming higher after menopause, which showed a U-shaped trajectory. When compared adiponectin levels in late postmenopausal group [(13 ± 5) mg/L] with those in perimenopausal [(8 ± 6) mg/L] or early postmenopausal group [(9 ± 6) mg/L], it all showed significantly difference (P<0.05). (2) Both the adiponectin levels were negatively correlated with waistline in the 4 groups (premenopausal group, r=-0.276;perimenopausal group, r=-0.334;early postmenopausal group, r=-0.211;late postmenopausal group, r=-0.218; all P<0.05). Levels of adiponectin were positively correlated with SHBG (r=0.536, P<0.05) and negatively with FAI (r=-0.363, P<0.05) in menopausal transition, while in late postmenopausal group, negatively correlated with level of DHEA-S (r=-0.450, P<0.05). When adjusted for age, BMI and waistline, the above correlations still exist. Conclusions Adiponectin levels declined to its lowest level in menopausal transition and gradually becoming higher after menopause, which showed a U-shaped trajectory during the sequential menopause status transition in middle aged women. Low level of adiponectin in menopausal transition is closely associated with the relative excess androgen occurred during this stage.

BACKGROUND: Previous studies have proved platelet-rich fibrin (PRF) with osteoinduction ability, and the centrifugal speed and time to prepare rabbit advanced PRF (A-PRF) with the most similar structure to that of human PRF have been determined.OBJECTIVE: To observe the histological changes during A-PRF-induced osteogenesis.METHODS: Thirty Japanese white rabbits were randomly divided into A-PRF and blank control groups (n=15 per group).The full-thickness defect models were established on the rabbit parietal bone, followed by implanted with A-PRF or nothing, respectively. The model rabbits were killed immediately, at 2, 4, 8 and 12 weeks after modeling, to grossly observe the bone formation, and the histological changes in the defect region were observed through hematoxylin-eosin staining, Masson staining and immunohistochemistry.RESULTS AND CONCLUSION: Unhealed defects were observed in the blank control group. Gross and histological observations showed that the speed, amount and maturity of bone formation in the A-PRF group were significantly better than those in the blank control group immediately, 4, 8 and 12 weeks after modeling (P < 0.05). Our findings suggest that the rabbit skull bone defect is successfully established. A-PRF can induce osteogenesis, and more mature newly born bones appear with time. Additionally, osteoclasts can act with osteoblasts synergically under the A-PRF induction to promote the bone formation.
