As a low-and middle-income country, Cuba has successfully implementedUniversal Health Coverage ( UHC) in the true sense, of which the major health indicators and human development index are relatively high. Moreover, many aspects of Cuba's healthcare system are worth learning from, especially constructing family doctor system, integrating medicine policy into national economic and social development strategies, focusing on drug re-search and development, standardizing high-quality medical education, etc.

Objective To evaluate the effect of lifestyle intervention on the indexes of patients with dyslipidemia.Methods CNKI,Wanfang Database,VIP,PubMed,Web of Science,EBSCO,EMbase,the Cochrane Library,Clinical Trials,MEDLINE were retrieved.The search terms included lifestyle intervention,lifestyle,diet,physical activity,dyslipidemia,hypercholesterolemia,lipid,low fat diet,plant sterols,low-glycemic index(GI)diets,mono-unsaturated fatty acids.Articles on randomized controlled trials(RCTs)to study the effect of lifestyle intervention on the indexes of patients with dyslipidemia were screened according to inclusion and exclusion criteria.Meta-analyses were conducted by using RevMan 5.3 software after extracting data.Results 19 articles were internalized,including 2 294 patients(intervention group,n=1,170)and(control group,n =1,124).According to the results of intervention group versus control group,total cholesterol of weighted mean difference(WMD)was (-0.61,95 ％CI.-0.84～-0.38,P＜0.01),triglyceride of WMD was(-0.28,95 ％ CI:-0.42～ 0.15),P＜0.01),low-density lipoprotein cholesterol of WMD was (-0.45,95 ％ CI:-0.72 ～ 0.18,P ＜0.01),(all P＜0.01),with significantly lower WMD in intervention group than in control group.The high-density lipoprotein cholesterol of WMD was (-0.05,95 ％ CI:-0.22 ～ 0.12,P =0.59),the difference was not significant.Conclusions Lifestyle intervention improves serum levels of total cholesterol,triglyceride and low-density lipoprotein cholesterol for dyslipidemia patients,but its effect on high-density lipoprotein cholesterol is not significant.

Objective To investigate the possibility of measuring ABO blood group antibody levels using renal cortical tubular epithelial cells (RCTECs) of cynomolgus monkey.Method The primary RCTECs were isolated from cynomolgus monkey kidneys and identified by Western blotting and flow cytometry (FACS).FACS was applied to detect the expression of ABO histo-blood group antigens on RCTECs,the binding of blood group antibodies in human serum to RCTECs,and to compare the difference of measuring ABO blood group antibody levels between using human erythrocytes and RCTECs as target cells.Result The majority of cells derived from the kidney cortex were renal tubular epithelial cells.39.90％-73.80％ of RCTECs were found to express the ABO histoblood group antigens with the capability to bind the human blood group antibodies specifically.The expression level of ABO histo-blood group antigen on RCTECs was not influenced by long-term cryopreservation,and the percentage of B antigen positive cells was 39.90％ before frozen storage and 39.65％ after a 10-month cryopreservation respectively.The normal serum and allergic serum presensitized to synthetic A antigen-keyhole limpet hemocyanin (KLH-A) of cynomolgus monkey were used to compare the abilities of RCTECs and human erythrocytes to detect antibody titers.No agglutination was observed in RCTECs test group.The mean fluorescence intensity (MFI) values of antibody were highest when the dilution fold was lowest (1 ∶ 16) and gradually decreased with increased serum dilution in both serum groups.MFI fell towards baseline value at 1 ∶ 128 dilution in normal serum group while at 1∶8 192 dilution in allergic serum group.Between 1 ∶ 16 and 1∶8 192 dilutions,MFIs of normal serum group were all lower than those of allergic serum.In human red cells test group,obvious agglutination appeared at high concentrations of antibodies,and MFIs reached the peak at 1∶64 dilution in normal serum group and at 1∶32 dilution in allergic serum group,but fluctuated irregularly thereafter.Between 1∶64 and 1∶512 dilutions,MFIs of normal serum group were all higher than those of allergic serum.Data above showed that MFI values in RCTECs group could reflect the levels of blood group antibodies more exactly.Conclusion The RCTECs of cynomolgus monkey express ABO tissue-blood group antigens and would be more suitable to be used to measure ABO blood group antibody levels by FACS.

In order to simultaneously remove carbon and nitrogen from organic-rich wastewater, we used an up-flow anaerobic sludge bed/blanket (UASB) reactor that was started up with anammox with high concentration of carbon and nitrogen by gradually raising the organic loading of influent. We optimized the removal of nitrogen and carbon when the chemical oxygen demand (COD) concentration varied from 172 to 620 mg/L. During the entire experiment, the ammonium and total nitrogen removal efficiency was higher than 85%, while the average COD removal efficiency was 56.6%. The high concentration of organic matter did not restrain the activity of anammox bacteria. Based on polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) and tapping sequencing analyses, the Planctomycete, Proteobacteria, Chloroflexi, Chlorobi bacteria are detected in the UASB reactor, which indicated complex removal pathway of carbon and nitrogen coexisted in the reactor. However, a part of Planctomycete which referred to anammox bacteria could tolerate a high content of organic carbon, and it provided help for high performance of nitrogen removal in UASB reactor.

To study the enrichment regulation of anammox bacteria during the whole start-up process of anammox reaction, two reactors with addition of carries of Spherical Plastic (SP) and Bamboo Charcoal (BC) and one without carrier (CK) were used to start anammox reaction. Then FISH and q-PCR analyses for the growth of all anammox bacteria were conducted during the operational process. The results indicate that the number of anammox bacteria in all reactors increased with time during the whole start-up process, which was consistent with the removal rate of ammonium and nitrite. On day 123 of stable phase, the percent of anammox cells in the sludge of CK, SP and BC accounted for 23.3%, 32.6% and 43.7%, respectively. The number of anammox bacteria 16S rRNA gene copies was (25.64 +/- 2.76) x 10(7), (47.12 +/- 2.76) x 10(7) and (577.99 +/- 27.25) x 10(7) copies g(-1) VSS in the sludge of CK, SP and BC, respectively. Carrier addition could dramatically increase enrichment of anammox bacteria. BC addition significantly increased the anammox bacteria number in the UASB reactor which resulted in the acceleration of the anammox start-up process. In addition, the max specific growth rate and the minimum doubling time were 0.064 d(-1) and 10.8 d in BC reactor. The max specific growth rate of anammox bacteria in BC reactor was 1.78 times and 1.88 times greater than that in CK and SP reactor, respectively. Therefore, the FISH and q-PCR analyses were suitable for determining the enrichment regulation of anammox bacteria during the start-up time, while a bit of differences in results existed between the two analytical methods due to the difference in analysis targets.

Objective To compare the clinical efficacy and the adverse reaction of transcatheter arteri-al chemoembolization( TACE)alone and combined with stereotactic body radiation therapy( SBRT)in patients with primary hepatic carcinoma by a Meta-analysis. Methods PubMed,Cochrane Library,EMBase,Ovid, MEDLIN,CNKI,CBMdisc,VIP and Wanfang were searched to identify the controlled clinical trials of TACE and SBRT for primary hepatic carcinoma. The obtained data were analyzed using Review Manager version 5. 2 provided by Cochrane Collaboration. To analysis the short-term effect of TACE alone or combined with SBRT, the rate of local tumor control and the difference of one,two,three and five-year survival rate. Results A total of 1 143 patients from 10 controlled clinical trials were involved according to the inclusion criteria. The Meta-analysis showed that TACE and SBRT group significantly increased the short-term effective rate,the rate of local tumor control,l-,2-,3-and 5-year overall survival rates(RR=1. 43,95%CI:1. 32-1. 56,P﹤0. 000 01;RR=2. 09,95%CI:1. 63-2. 69,P﹤0. 000 01;RR=1. 31,95%CI:1. 21-1. 42,P﹤0. 000 01;RR=1. 46, 95%CI:1. 23-1. 72,P﹤0. 000 01;RR=1. 76,95%CI:1. 14-2. 71,P=0. 01;RR=2. 29,95%CI:1. 22-4. 32, P=0. 01). There was no statistically significant difference between the two groups on adverse events such as leucopenia(RR=0.97,P =0. 61),thrombocytopenia(RR =0. 99,P =0.85),hemoglobin decrease(RR =0. 95,P=0. 63),nausea and vomiting(RR=1. 00,P=0. 98),liver function damage(RR=0. 98,P=0. 87). Conclusion Compared with TACE,TACE combined with SBRT can increase the short-term effective rate,the rate of local tumor control,the 1-,2-,3-and 5-year overall survival time of the patients,and does not increase the incidence of adverse reaction. However high-quality trials with large sample sizes are still needed to verify the long-term efficacy and safety.

Objective: To investigate the efficacy and safety of oxycodone hydrochloride prolonged-release tablets and tramadol hydrochloride sustained-release tablets in the treatment of moderate cancer pain. Methods:Totally 290 cases of the patients with mod-erate pain were divided into the observation group with 148 cases and the control group with 142 cases. The observation group received oxycodone hydrochloride prolonged-release tablets, while the control group was given tramadol hydrochloride sustained-release tablets. The treatment course was 2 weeks, and the total efficiency and the incidence of adverse drug reactions( ADR) in the two groups were calculated and compared. Results:The total efficiency in the observation group and the control group was 92. 6% and 81. 7%, respec-tively, and the difference was statistically significant (P<0. 01). The incidence of ADR was 60. 1% and 57%, respectively with no significant difference (P>0.05). Conclusion: The effect of oxycodone hydrochloride prolonged-release tablets in the treatment of moderate cancer pain is better than that of tramadol hydrochloride sustained-release tablets.

A quality control (QC) strategy for quantitative and qualitative analysis of “common peaks” in chemical fingerprint was proposed to analyze Yuanhu Zhitong tablet (YZT), using high performance liquid chromatography with diode array detector and tandem mass spectrometry (HPLC-DAD-MS/MS). The chromatographic separation was achieved on an Agilent Eclipse plus C18 column with a gradient elution using a mixture of 0.4‰ ammonium acetate aqueous (pH 6.0 adjusted with glacial acetic acid) and acetonitrile. In chemical fingerprint, 40 peaks were assigned as the “common peaks”. For quantification of “common peaks”, the detection wavelength was set at 254 nm, 270 nm, 280 nm and 345 nm, respectively. The method was validated and good results were obtained to simultaneously determine 10 analytes (protopine, jatrorrhizine, coptisine, palmatine, berberine, xanthotoxin, bergapten, tetrahydropalmatine, imperatorin and isoimperatorin). For qualification of “common peaks”, 33 compounds including 10 quantitative analytes were identified or tentatively characterized using LC-MS/MS. These results demonstrated that the present approach may be a powerful and useful tool to tackle the complex quality issue of YZT.
