Abstract: Malaria, an infectious disease caused by Plasmodium infection, is one of the most important public health problems worldwide. Artemisinin-based combination therapies (ACTs) are recommended by WHO as the first-line treatment for uncomplicated P. falciparum malaria in malaria-endemic areas. The application of artemisinin and its derivatives has played an integral role in reducing the global incidence of malaria. However, in recent years, the emergence and spread of artemisinin resistance has brought great challenges to global malaria control and elimination. At present, the mutation of K13 gene on chromosome 13 of Plasmodium falciparum is most closely related to artemisinin resistance, but in recent years, studies have shown that K13 cannot explain all artemisinin resistance. This article reviews the recent research progress in the field of artemisinin resistance in Plasmodium falciparum, including definition of artemisinin resistance, detection methods and molecular markers related to resistance. In addition, some of the issues discussed in this review remain controversial and require further study.

Objective To investigate the protective effect of carnosine on Glutamate induced apoptosis in SH-SY5Y cells and its mechanism. Methods The injury model was established by treating SH-SY5Y cells with glutamate in vitro.Inverted microscope was used to observe cell morphology. The cell viability was detected by MTT assay, and changes in nucleus were detected by Hoechst33258 staining under fluorescence microscopy.The cell apoptosis rates were measured by flow cytometry.The reactive oxygen species ( ROS ) level in cells was detected by fluorescent probe CDFH-DA. Results Compared with normal control group, the cell viability in glutamate group decreased (P<0.01), the morphology changes of cell apoptosis such as karyopyknosis and split were observed by Hoechst33258 staining, while the apoptosis rate and the level of ROS were increased (P<0.01). Compared with glutamate group, the cell viability of carnosine 0.6,3,15 mmol/L groups obviously increased(P<0.01), while the morphology changes of cell apoptosis significantly improved, the apoptosis rate and the level of ROS were obviously reduced ( P<0.01 ) .Compared with normal control group, the cell viability, the morphology changes and the apoptosis rate did not significantly change in carnosine group.The level of ROS was reduced, but there was no statistically significant difference between two groups.Conclusion Carnosine has apparent protective effect on apoptosis of SH-SY5Y cells injury induced by glutamate.The mechanism may be related to carnosine prevent the occurrence of oxidative stress.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

Background and purpose: Ursolic acid is widely present in spica prunellae, hedyotis diffusa and other heat antidotes. The growth of a variety of tumor cells can be inhibited and induced apoptosis by ursolic acid.This study was aimed to investigate the effect and possible mechanisms of UA on inducing apoptosis of human gastric carcinoma BGC823 cells. Methods: The MTT assay was used to detect the antiproliferative effect of UA on BGC823 cells. Flow cytometry was used to detect cell cycle and apoptosis of BGC823 cells. The expression level of bcl-2 and bax gene was investigated by real time-polymerase chain reaction (real time-PCR). Results: UA inhibited the proliferation of BGC823 cells in a dose and time-dependent way. After treatment by UA for 24. 48 and 72 h, the IC_(50) of BGC823 was 36.88, 34.72, and 32.18 μmol/L, respectively. UA could signifcantly induce apoptosis of BGC823 cells and block cells at G_2/M phase. UA could increase the expression of bax gene and decrease the expression of bcl-2 gene in a dose and time-dependent way. Conclusion: UA could induce apoptosis and inhibit the proliferation of BGC823 cells in a dose and time-dependent way. It could arrest cell cycle of BGC823 cells at G_2/M phase. Its mechanisms might be associated with the up-regulation of bax gene and down-regulation of bcl-2 gene.
