OBJECTIVE:To systematically review the efficacy of Duhuo jisheng decoction combined with chemical medicines in the treatment of ankylosing spondylitis (AS),and to provide reference for clinical treatment. METHODS:Retrieved from CBM,CJFD,VIP,Wanfang Database,PubMed and EMBase,randomized controlled trials(RCT)about Duhuo jisheng decoction combined with chemical medicines(test group)versus chemical medicines alone(control group)in the treatment of AS were col-lected,Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Total-ly 6 RCTs were included,involving 382 patients. Results of Meta-analysis showed,the total effective rate [RR=1.35,95%CI(1.20, 1.52),P<0.001],improvement rate of TCM symptoms [RR=1.31,95%CI(1.09,1.57),P=0.004)in test group were significantly higher than control group,and CRP level was lower than contxol group[MD=-6.18,95%CI(-8.49,-3.87),P<0.001],the dif-ference was statistically significant. CONCLUSIONS:Duhuo jisheng decoction combined with chemical medicines shows better effi-cacy than chemical medicines alone,it can improve the TCM symptoms and decrease the CRP level.

Objective To determine whether ultrasound (US) exposure combined with microbubble destruction could be used to enhance non-viral gene delivery in rat C6 glioma cells. Methods Microbubbles were prepared and gently mixed with plasmid DNA. The mixture of the DNA and microbubbles was administered to cultured C6 cells under different US/microbubble conditions. US parameters adopted in this study were frequency 1 MHz, output intensity 1 W/cm2, duty cycle 20%, exposure time 30 seconds. Transfection efficiency and cell viability were assessed by FACS analysis, confocal laser scanning microscopy, and Try pan blue staining. Results Microbubble with US exposure could significantly enhance the reporter gene expression as compared with other groups. No statistical significant difference was observed in the glioma cell viability between different groups. Conclusions US-mediated microbubble destruction has the potential to promote safe and efficient gene transfer into C6 cells,and it may be useful for safe clinical gene therapy of brain cancer without a viral vector system.

Objective To study the accuracy of an ultrasonographic characteristic diagnostic score system(UCDSS) which was used to classify the breast solid nodular lesions. Methods UCDSS were established by analyzing the ultrasonographic sign of the 205 breast solid nodular lesions. These lesions were classified according to the total scores of each ultrasonographie sign. ROC curve was used to evaluate the value of UCDSS. Results The area under ROC curve of UCDSS was 0. 977, the sensitivity and specificity was 92.0%, 92.3% respectively. Conclusions The classification based on the UCDSS may increase the diagnostic accuracy of the differentiation between benign and malignant breast solid nodular lesions.

Objective To investigate the role of neuroglobin ( NGB) in oxygen-glucose deprivation and reoxygenation ( OGD/R ) induced mitochondrial depolarization and reactive oxygen species ( ROS ) production in a human neuroblastoma cell line (SH-SY5Y).Methods SH-SY5Y cells were transfected with lentivirus to establish a stable cell line of NGB knockdown ( KD).After treated with OGD/R, cells were collected at different time points to analyze NGB mRNA and protein levels.Furthermore, cells were stained with JC-1 and DCFH-DA to evaluate mitochondrial depolarization and ROS production by inverted fluorescence microscope.Also, to determine the neurotoxicity , we measured the lactate dehydrogenase ( LDH) level in the cell culture medium.Results After the treatment of OGD/R, the NGB mRNA and protein started to elevate and peak at 4 h and 8 h (2.04 ±0.35 fold,1.69 ±0.18 fold).Compared with the vector group , NGB KD group had much more mitochondrial depolarization [ JC-1 red/green ( 1.10 ±0.10 ) vs (1.46 ±0.11),P<0.05] and ROS production [DCFH-DA fluorescence (36.30 ±5.32) vs (16.26 ± 2.97),P<0.05].Furthermore, NGB KD groups had a higher level of LDH release [(63.42 ±6.14)%vs (49.65 ±5.09 )%, P <0.05 ].Conclusions NGB plays an important role in the homeostasis of mitochondria.Knockdown of NGB results in increased mitochondrial depolarization , ROS production and neurotoxicity under hypoxia circumstances.

Objective To evaluate the clinical outcomes of severely resorbed edentulous mandibles with tilted implants and fixed prostheses. Methods Ten patients with severely resorbed edentulous mandibles were en-rolled. Each patient received 4 implants,two posteriors placed tilted implants. Immediate loading of tilted implants were applied in all cases using a fixed provisional prosthesis. All patients were finalized 3-4 months with fixed pros-theses. Results 40/40 implants with initial torque(>35N.cm)were followed 1-1.5 years presenting 100%surviv-al. Conclusion The method of using tilted implants and fixed prostheses in the cases of severely resorbed edentu-lous mandibles can achieve an ideal short-term and medium-term effects.

OBJECTIVETo observe the influence of ingredients in Xingnaojing,such as moschus, borneol and radix curcumae on intestine absorption kinetics of gardenia extract.

METHODAn in situ intestinal perfusion model of rats was employed to investigate the absorption of geniposide in gardenia extract.

RESULTWhile gardenia extract was administered solely, the absorptive rate constant (K) of geniposide was (0.055 +/- 0.006) h(-1); But while the extract was co-administered with radix curcumae,moschus and borneol, the K were (0.060 +/- 0.001), (0.066 +/- 0.008), (0.072 +/- 0.010) h(-1), respectively. The K was (0.076 +/- 0.011) h(-1) while the extract in total formulation for Xingnaojing.

CONCLUSIONThe K, while the extract is co-administered with borneol or total formulation is significantly higher than solely used. Borneol and complex prescription can significantly increase the intestinal absorption of geniposide in gardenia extract.

Objective: To explore the diagnostic values of FibroTouch and FibroScan for liver fibrosis in patients with chronic hepatitis B(CHB). Methods: This study enrolled patients with CHB who was accepted liver biopsy at Beijing Friendship Hospital, Capital Medical University between March 2014 to December 2017. FibroTouch and FibroScan were performed among these patients at same time. Liver stiffness measurement(LSM), optimal cut-off value, receiver operating characteristic(ROC) were compared. Results: In our 103 patients, there were no significantly different between FibroTouch and FibroScan in LSM. The threshold of the optimal cut-off value for FibroTouch and FibroScan were 5.45 versus 5.55 kPa (≥S1), 7.10 versus 6.65 kPa (≥S2), 11.05 versus 9.20 kPa (≥S3), 15.50 versus 15.45 kPa (S4), respectively. The area under the ROC curve for the prediction of the stage1, stage2, stage2, stage 4 of liver fibrosis in these patients were 0.858 versus 0.765 (P=0.54), 0.812 versus 0.801 (P=0.68), 0.863 versus 0.878 (P=0.45), and 1.0 versus 0.99 (P=0.38) respectively. Conclusions FibroTouch and FibmScan have a good consistency in the evaluation of the degree of liver fibrosis in patients with CHB.

Objective: This study aimed to systematically evaluate potential causal relationships between nine cathepsins and female infertility using Mendelian randomization (MR) methods. Methods: A bidirectional MR analysis was conducted utilizing single nucleotide polymorphisms as instrumental variables to investigate the potential causal effects between nine cathepsins and female infertility. Genetic data on female infertility were sourced from the FinnGen study, and cathepsin-related data were obtained from genome-wide association studies datasets of European ancestry. Results: Elevated levels of cathepsin E were significantly and inversely associated with the risk of female infertility, suggesting a potential protective role. This finding was further supported by multivariable MR analysis. However, no significant associations were observed between the other eight cathepsins and female infertility. Conclusion This study represents the first systematic MR analysis to identify a potential protective effect of cathepsin E on female infertility.
