The effects of betulinic acid (BA), a pentacyclic lupane-type triterpene, on the cell viability, cell cycle and apoptosis in human leukemia K562 cells were investigated. The effects of BA on the growth of K562 cells were studied by MTT assay. Apoptosis was assayed through Annexin V/propidium iodide (PI) double-labeled cytometry. The effects of BA on the cell cycle of K562 cells were studied by a PI method. The expression of Bax and capase-3 was detected by using Western blot. The results showed that BA was cytotoxic to K562 cells with an IC(50) of 21.26 mug/mL at 24 h. After treating K562 cells with 10 mug/mL BA for 72 h, the number of cells was reduced by 58%. BA induced apoptosis of K562 cells in a time- and dose-dependent manner. The proportion of cells in G(0)/G(1) and G(2)/M phases was decreased and that in S phase was increased after K562 cells were treated with BA for 24 h. BA treatment also increased the expression of the pro-apoptotic proteins Bax and caspase-3. It suggested that BA could inhibit the proliferation of K562 cells through the induction of cell cycle arrest and apoptosis. The antitumor effects of BA were related with up-regulation of the expression of Bax and caspase-3 proteins. BA may qualify for the development of new therapies for leukemia.

OBJECTIVETo study the clinical efficacy of Chinese herbal retention enema combined with intrauterine douching for patients with endometritis diagnosed by hysteroscopy. They failed in in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET) treatment.
METHODS131 patients received hysteroscopy after they failed in routine IVF/ICSI-ET treatment. Of them, 66 patients diagnosed as endometritis were enrolled as the test group and 65 patients without endometritis were enrolled as the control group. Chinese herbal retention enema combined with intrauterine douching was performed on patients in the test group before the next IVF/ICSI, while direct IVF/ICSI was performed on those in the control group. The embryo implantation rate and the clinical pregnancy rate were compared between the two groups.
RESULTSThe clinical pregnancy rate and the embryo implantation rate were 48.5% and 24.2% respectively, while they were 29.2% and 14.9% respectively in the control group, showing significant difference (P < 0.05).
CONCLUSIONChinese herbal retention enema combined with intrauterine douching could improve the embryo implantation rate and the clinical pregnancy in patients with endometritis.

BACKGROUND:The brain mechanism of semantic processing is one of the focus problems in cognitive neuroscience.With the research technologies plentiful and diversified, the brain mechanism of semantic processing is gradually distinct.However, at present, the related researches on Chinese semantic processing are not enough. The brain mechanism of semantic processing by Chinese language obstacle should be studied more deeply.OBJECTIVE: To further identify the neuropsychological significance of clinical diagnosis, treatment and rehabilitation by concluding the study fruits on the brain mechanism of semantic processing by native Chinese speaker with dysphonia and analyze the relationship between the related brain mechanism and the local brain system of semantic processes as well as brain anatomical parts.RETRIEVE STRATEGY: The retrieve staffs are the research personnel for this paper. The range of retrieve time focuses since 1984. A computer-based online search was conducted in CNKI for literatures related to basic neuropsychology and its clinical application published between January 1994 and May 2006, in Elsevier for articles between January 1984 and May 2006, in Academic Source Premier and MEDLINE of EBSCOhost for studies between January 1984 and May 2006 with the key words of "semantic processing", and the language was limited to English. Meanwhile, relevant data were searched manually. The number of total retrieved articles was 264, among which 43 enrolled studies were in accordance with the inclusion criteria and excluded articles involving semantic processing or encephalic region but without their relationship. The unpublished articles were only used for references LITERATURE EVALUATION: The literatures are selected from related works, collected analyses, reports from single case or research. Evaluated persons are related research staffs.DATA SYNTHESIS: Processing of Chinese semantic relied primarily on the left superior temporal region, middle temporal gyrus, the inferior gyrus of frontal regions as well as the left middle frontal gyrus, which make up a frontal-temporal network for semantic processing. Lexical-semantic processing is strongly correlated with activation in the posterior portion of left superior temporal region and the middle temporal gyrus, which appear to be responsible for storage and automatic of semantic processing. The anterior temporal region is related to integrate different semantic knowledge. More strategic processes and those that require specific memory resources may be represented in the inferior frontal cortex. In addition, the left middle frontal gyrus is special to Chinese semantic process, and some scholars infer the reason is the unique style of Chinese characters.CONCLUSION: At present, there are many methods to study neuropsychology, brain tissues and its functions, with which a great deal of neuropsychological disorder and mechanism of pathological changes in clinic can be studied and comprehended more distinctly, and all these are greatly helpful to the treatment and rehabilitation.

OBJECTIVETo verify the regulatory effects of acupuncture on exercise tolerance in patients with chronic obstructive pulmonary disease (COPD) at stable phase.
METHODSThirty cases of COPD were randomly divided into a treatment group (16 cases) and a placebo group (14 cases). Based on specified aerobic exercise, acupuncture was applied in the treatment group and placebo acupuncture was used in the placebo group. The acupoints included Danzhong (CV 17), Rugen (ST 18), Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25) and so on. The needle did not penetrate into the skin for the placebo group. The treatment was required for 2 to 3 times per week for totally 5 weeks. The indices of exercise tolerance, including 6-min walking distance (6-MWD), exercise time, maximum oxygen uptake (VO2max) forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC), maximum ventilatory volume (MVV), St. George respiratory questionnaire (SGRQ) were observed in two groups before and after treatment.
RESULTS(1) Exercise tolerance: the differences of 6-MWD and exercise time were statistically significant between groups, which were more superior in the treatment group (both P<0.01); the VO2max was significantly increased after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05). (2) Pulmonary ventilation function: the differences of FEV1%, FEV1/FVC and MVV% were statistically significant between groups, which were more superior in the treatment group (P<0.05, P<0.01); (3) SGRQ: the SGRQ was significantly improved after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05).
CONCLUSIONThe acupuncture could improve the exercise tolerance in patients with chronic obstructive pulmonary disease at stable phase, and shorten the onset time of aerobic exercise. Besides, acupuncture combined with aerobic exercise could effectively improve the pulmonary function.
