OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

Objective To observe the effect of bilateral movement training on upper extremities dysfunction in stroke patients in convalescent phase. Methods 52 patients with hemiplegia were randomly divided into treatment group (n=26) and control group (n=26). The treatment group accepted bilateral upper extremities movement training, and the control group accepted routine neurodevelopment training mainly with affected upper extremities, for 6 weeks. They were assessed with Fugl-Meyer Assessment upper-extremity section (FMA-UE) and modified Barthel Index (MBI) before and after treatment. Results The FMA-UE and MBI scores improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.001). Conclusion Bilateral movement training may improve upper extremity function and activities of daily living more effectively for stroke patients in convalescent phase.

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.

OBJECTIVETo select an effective way to enhance vigor of Prunella vulgaris seeds.

METHODThree population seeds were treated at the 20 degrees C and dark enviroment.

RESULTPriming with 20% - 30% PEG and 200 - 400 mg x L(-1) GA3 could enhance seeds germination and vigor. Germination percentage of three population seeds treated with 0. 6% - 3.0% NaCl reduced, but they started to germinate in advance. Treated with 0.6% - 2.4% KNO3-KH2PO4, germination rate and vigor of seeds in Zijinshan and Pan' an both increased and the one in Bozhou decreased.

CONCLUSIONVigor of P. vulgaris seed treated with PEG and GA3 under proper concentration increases, while treated with KNO3-KH2PO, and NaCl low vigor seeds germination rate reduces.

AIMTo study the protective effects of hydroxyethylpuerarin against the injury of astrocytes induced by hydrogen peroxide (H2O2).

METHODSExperiments were performed with cells from passage 4. Plasma membrane integrity was measured by lactate dehydrogenase (LDH) release. The occurrence of apoptosis was measured by flow cytometry. The glutamate uptake of astrocytes was studied with [3H]-glutamate incorporation. Intracellular superoxide dismutase (SOD) activity and malondialdehyde (MDA) level were assessed by automatic biochemistry analyzer.

RESULTSCompared with H2O2 injured group, the occurrence of apoptosis, levels of LDH release and intracellular MDA of astrocytes reduced in hydroxyethylpuerarin pre-treated groups, but the glutamate uptake and intracellular SOD activity of astrocytes increased.

CONCLUSIONHydroxyethylpuerarin could reduce the occurrence of apoptosis and improve neurotrophic function of astrocytes, which may be related with its antioxidant effects during oxidative stress.

The aim of this study is to investigate the effect and mechanism of angiotensin (Ang) II on E-selectin and vascular cell adhesion molecule-1 (VCAM-1) expression in rat brain microvascular endothelial cells (BMEC) and evaluate the effect of compound EXP-2528, a novel Ang II type 1 (AT1) receptor antagonist. The experiment was performed in cultured BMEC of rat. The mRNA and protein expression of E-selectin and VCAM-1 in BMEC was analyzed by RT-PCR and Western blotting, respectively. The results showed that the mRNA and protein expression of E-selectin and VCAM-1 in BMEC were significantly upregulated by 4 h or 18 h exposure to 1 x 10(-7) mol x L(-1) Ang II. These effects were abolished by pretreatment with the selective AT1 receptor antagonists losartan and compound EXP-2528, but not with the AT2 selective antagonist PD123319. Combining losartan with PD123319 also significantly inhibited Ang II-induced E-selectin and VCAM-1 expression in BMEC, but there was no significant difference compared with losartan group. These findings indicated that Ang II upregulated E-selectin and VCAM-1 in BMEC by activating AT1 receptor and then involved in the development of cerebrovascular disease.

Cellular senescence is one of the important steps against tumor. This study was to observe the characteristics of boningmycin induced senescence of human tumor cells. MIT method and clone formation assay were used to detect the growth-inhibitory effect. Cellular senescence was detected with senescence-associated beta-galactosidase staining. Cell cycle distribution and accumulation of intracellular reactive oxygen species (ROS) were analyzed with flow cytometry. Protein expression was detected by Western blotting. The results showed that the growth-inhibitory effect of boningmycin was obviously stronger on human oral epithelial carcinoma KB cells than that on non-small cell lung cancer A549 cells. Comparison to the similar action of doxorubicin, that boningmycin induced the features of cellular senescence in both cell lines, its due to the arrest at G2/M phase and an increase of ROS level. The molecular senescence marker P21 increased significantly after boningmycin treatment at a dosage of 0.1 micromol x L(-1), whereas a higher concentration of it induced apoptosis. The results indicated that cellular senescence induced by boningmycin was one of its mechanisms in tumor suppression.

OBJECTIVETo explore the molecular mechanism of Qiangxin Fumai granule (QFG, an effective Chinese composite drug) in preventing and treating sick sinus syndrome (SSS).

METHODRabbit model of sinoatrial ischemia/reperfusion was established by occluding and loosening the root of right coronary artery. Effect of QFG on cell apoptosis was observed by TUNEL method, and its effect on apoptotic related gene Bax, Bcl-2 and Fas-L gene protein expression was observed by immunohistochemical method. Average light density values of the expression of Bax, Bcl-2 and Fas-L of SAN cells was determined by Imagepro Plus image analysis system.

RESULTSinoatrial injury induced by ischemia/reperfusion could cause evident sinoatrial cell apoptosis, enhance Fas-L gene protein expression and obviously enhance Bax gene protein expression, reduce Bcl-2/Bax ratio. QFG could significantly down-regulate Fas-L and Bax gene protein expression, up-regulate Bcl-2/Bax ratio, significantly inhibit and block the sinoatrial cell apoptosis.

CONCLUSIONTo inhibit and block the event of cell apoptosis through regulating Bax, Bcl-2 and Fas-L gene protein expression in sinoatrial node after ischemia/reperfusion might be one of the mechanisms of QFG in preventing and treating sinoatrial ischemia/reperfusion injury of SSS.

This article describes the experiences of professor CHEN Quan-xin, an old famous TCM doctor, in the treatment of insomnia. He believes that insomnia stems from incoordination between nutrient qi and defensive qi and deficient cultivation of cardiac spirit, and treatment of insomnia need to regulate spirit and quiet heart coherently. Painless acupuncture method of Chen's flying needling is adopted including to select Shenmen (HT 7), Sanyinjiao (SP 6) and Anmian (Extra) as the main points and take special needling technique and grading reinforcing and reducing manipulations. During treatment, he pays attention to understanding patients' psychological and mental status through "watching one's expressions and weighing his words carefully".
