Objective To observe the expression level of HOXB6 gene on the differentiation and proliferation of hematopoietic stem cells(HSC) to colony forming unit-granulocyte-monocyte(CFU-GM),erythroid progenitor(CFU-E) and colony forming unite-T-lymphocyt(CFU-TL).And the proliferation procress was affected by all-transretinoic acid(ATRA).Methods 1.By the colony culture in vitro,the impact of ATRA on the CFU-GM,CFU-E,CFU-TL colony formation were surveyed;the expressions of HOXB6 gene were observed on the differentiation procress of HSC to CFU-GM,CFU-E and CFU-TL affected by ATRA on the 3rd,7th,12th.2.Real-time fluorogenic quantitative reserve transcription-polymerize chain reaction(FQ-RT-PCR) method was used to explore the possible mechanism of ATRA up-regulated to human cord blood CFU-GM,CFU-E and CFU-TL in gentic level.Results 1.HOXB6 gene had a regulatory function in the differentiation procress of hematopoiesis.During the differentiation and proliferation of HSC to colony forming CFU-GM or CFU-E,CFU-TL in vitro,the expressions of HOXB6 gene were significant positive.2.Compared with the expressions of CFU-GM and CFU-TL HOXB6 mRNA on day 3,the quantity of HOXB6 mRNA was obviously higher on day 7 and lower on day 12,respectively in each group.Compared with the expression of CFU-E HOXB6 mRNA on day 3,the quantity of HOXB6 mRNA was obviously higher on day 12 in each group.3.Compared with the HOXB6 gene of control group,the expressions of HOXB6 gene of group ATRA were up-regulated remarkable.Conclusions 1.HOXB6 gene has a regulatory function in the differentiation procress of hematopoiesis.HOXB6 gene plays an important role in the progress which can be associated with the regulating effect of HOXB6 gene on the differentiation and proliferation of CFU-GM,CFU-E and CFU-TL.2.During the differentiation and proliferation of HSC,the expression of HOXB6 gene is regular in time.3.Low concentration of ATRA(60 ?mol?L-1) can up-regulate the expression of HOXB6 gene,which confirms the theory that the normal hematopoie-tic lineage determination and maturation rely on the stable and consistent expression of HOXB6 gene.

?AlM: To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma.
?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) .
?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P<0. 05).
?CONCLUSlON:Good effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.

Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

Abstract: Objective　To evaluate the effects of sunitinib on Japanese encephalitis virus (JEV) infection in vitro and vivo. Methods　The 4-week-old BALB/c mice infected with JEV by intraperitoneal injection. The infected mice were treated with sunitinib for 5 days and 10 days respectively. After that, the change of weight and survival rate were evaluated continuously. The viral load variation in mice brain were detected by qRT-PCR. Indirect immunohistochemical staining assay (IFA) was used to detect the number and distribution of CD4+/CD8+T cells in mouse brain. IFA was also used to observe the expression of virus E protein in the brain of mice. Vero cells were infected with JEV in vitro and given a certain concentration of sunitinib to observe the cell survival status. The expression of virus E protein in cells was detected by IFA. Results　Continuous administration of sunitinib significantly improved the survival rate of infected mice. Survival rate and body weight changes showed that the 5-day's administration strategy was significantly better than the 10-day's administration strategy. The treatment of sunitinib decreased the infiltration of CD4+/CD8+T cells in the brain and reduced the changes of vascular sleeve. However, the variation of viral load and E protein expression in brain were not obvious. The cytopathic effect (CPE) of infected Vero cells were slightly relieved after giving sunitinib, and the expression of E protein was also slightly changed. Conclusion　Sunitinib can significantly reduce the mortality of infected mice, and the 5-day's administration strategy is significantly better than the 10-day's administration strategy. Sunitinib decrease T lymphocyte infiltration in brain of mice, relieve the encephalitis symptoms ,and prolonged the life of mice.

OBJECTIVEThere is little knowledge on whether there is clustering of inflammatory biomarkers, such as C-reactive protein (CRP), soluble intracellular adhesion molecule1-1 (sICAM-1), and angiotensin II (Ang II), in individuals with hypertension in the Mongolian population. In the present study, we investigated this relationship in a Mongolian population in China.

METHODSA total of 2589 adult Mongolians, aged 20 years and older, were recruited as study participants. Data on demographics, lifestyle, family history of hypertension, blood pressure, and blood chemistry were collected, and inflammatory biomarkers were measured in all participants.

RESULTSThe proportion of subjects with increased levels of two or three biomarkers was significantly higher in those with hypertension (21.0% and 6.0%, respectively) than in those with prehypertension (12.7% and 0.5%, respectively) or normotension (8.1% and 0.2%, respectively). The multivariate adjusted odds ratios (95% confidence interval) of hypertension associated with increased levels of one, two or three biomarkers were 0.94 (0.72-1.22), 1.42 (0.93-2.16), and 11.08 (1.45-84.80), respectively, compared with subjects with no increase in any biomarker.

CONCLUSIONHypertension was associated with a cluster of inflammatory biomarkers in the Mongolian population.
