The doctrine of"Five evolutive phases and six climatic factors"has a solid foundation of astronomy.In the traditional Chinese calendar,the years are designated by the circles of the Heavenly Stems and Earthly Branches,which reflects the cyclical regularity of the movement of the Sun,the Moon,the Earth and the stars.The cyclical movement brings up the qi transforming patterns(produce,growth,transformation,contraction and store)of the living things.The patterns are also the underlying foundation of human constitutional tendency.According to the Heavenly Stems and Earthly Branches of someone’s pregnant period and birth time,we could know the universe qi transforming characteristics of that time,thereby conjecture the constitutional tendency of the person.This is a very important way to research Chinese medical constitution.

Objective:To assess the expression of specific virulence-associated Helicobacter pylori (Hp) genotypes, (cag A, vac A, and ice A status) in primary gastrointestinal B cell lymphoma. Methods: Forty-nine paraffin wax embedded tissues were analyzed by immunohistochemical staining and poly-merase chain reaction. Results:There were 14 cases of mucosa associated lymphoid tissue lymphoma ( MALT-L) (8 in stomach, and 6 in intestine) and 35 cases of diffuse large B cell lymphoma (DLBCL) (21 in stomach, and 14 in intestine) in all. The positive rates of vac A s1 ,vac A s2 ,vac A m2,ice A 1 and cag A were 50. 0% ,42. 9% ,50. 0% , 14. 3% and 85. 7% in MALT-L; 57. 1% ,40. 0% ,25. 7% , 5.7% and91.4% in DLBCL, respectively. Conclusion:High toxicity cag A + Hp strains.seem to play a role in the pathogenesis of gastrointestinal B cell lymphoma, whereas vac A m2 may be more associated with MALT-L.

Acute phase is treated with clearing heat and resolving phlegm, cooling ying and nourishing yin; lag phase is treated with supplementing qi and nourishing yin, promoting blood circulation and resolving phlegm; anaphase is treated with nourishing lung and strengthening kidneys, resolving stasis and dredging collaterals.

Objective: To optimize the formula and preparation process of docetaxel-loaded pluronic P123 micelles. Methods:Docetaxel-loaded pluronic P123 micelles were prepared by a thin-film hydration method and optimized by central composite design and response surface methodology. The influencing factors including the quantity of docetaxel, volume of organic phase, volume of hydra-tion and temperature of hydration were investigated with the entrapment efficiency as the index. The morphology of micelles was ob-served under a transmission electron microscope. The particle diameter and zeta potential were determined. The in vitro release property was measured by a dialysis method. Results:The relationship between the influencing factors and the evaluation parameter was fitted by multi-linear equation, quadratic polynomial equation and cubic polynomial equation, respectively. The results showed that the cubic polynomial equation was superior to the others according to the correlation coefficient. Docetaxel-loaded pluronic P123 micelles were spherical with the mean diameter, zeta potential, polydispersity index, encapsulation efficiency and drug loading of 108. 3 nm,-3. 99 mV, 0. 265, (97. 91 ± 0. 28)% and (3. 72 ± 0. 12)%, respectively. The cumulative release in vitro reached 95. 03% in 120 h, and docetaxel-loaded pluronic P123 micelles had notable sustained-release property. Conclusion: The technical process for do-cetaxel-loaded pluronic P123 micelles is simple and usable, and docetaxel-loaded pluronic P123 micelles show high encapsulation effi-ciency and notable sustained-release property.

AIM:To observe the treatment for ptosis patients with severe undercorrection after frontal muscle flap suspension surgery. · METHODS: Totally 46 patients ( 67 eyes ) were randomly divided into 2 groups: 23 cases ( 33 eyes ) in Group A were given conjoint fascial sheath ( CFS ) suspension surgery; 23 cases ( 34 eyes ) in Group B Whitnall ligament suspension. Postoperative follow-up was 6mo. Corrected rate, recurrence rate and postoperative adverse reactions were compared and analyzed. ·RESULTS:The corrected rates of the two groups were both satisfied without significant difference between the two groups (P>0. 05). the Whitnall ligament suspension surgery had less recurrence than CFS suspension surgery, but the difference was not statistically significant (P>0. 05). The rate of hypophasis after CFS suspension surgery was significantly less than that after Whitnall ligament suspension (P<0. 05). ·CONCLUSION:The two operations both have satisfied corrected rate and low recurrence rate, the Whitnall ligament suspension surgery is less damaging and more easy to operate, while CFS suspension surgery is repeatable and less rate of hypophasis.

Objective To investigate the effects of DNMT1 on neuropathic pain behavior and neuropathic pain modulation.Methods Thirty-two male SD rats, weighing 200-250 g, were randomly assigned into 4 groups (n =8 each):sham operation group (group S),chronic constrictive injury group (group CCI),CCI+ DNMT1-siRNA group (group CDS),CCI+ control-siRNA group (group CCS).Group CDS were intrathcally injected of DNMT1-siRNA (2 μg/10 μl),and group CCS were intrathcally injected of control-siRNA 7,8,9 days after operation.Mechanical withdrawal threshold (MWT)and thermal withdrawal latency (TWL)were measured before operation and on day 3,5,7,9,12,14 after operation.The rats were then sacrificed and L4-L6 segments of the spinal cord were removed for determination of SOCS1,p-ERK,p-CREB expression using Western blot on day 14.Results Compared with group S,MWT and TWL in group CCI and CCS were significantly decreased on day 3,5,7,9,12,14 after operation (P <0.05).Compared with group CCS,MWT and TWL in group CDS were significantly increased on day 9,12,14 after operation (P < 0.05 ). Compared with group S and CDS,SOCS1 was significantly downregulated,p-ERK and p-CREB were significantly upregulated in group CCI and CCS (P <0.05 ).Conclusion Intrathcal injection of DN-MT1-siRNA significantly relieves neuropathic pain by upregulating SOCS1,downregulating p-ERK and p-CREB in rats spinal cords.

Objective: To investigate primary gastrointestinal B cell non Hodgkin’s lymphoma for clinicopathological features, proliferation, apoptosis and its association with Helicobacter pylori (HP). Methods: Classification of tumors, expression of HP, proliferation and apoptosis related gene products were studied by immunohistochemistry. Apoptosis was studied by TUNEL (TdT [terminal deoxynucleotidyl transferase] dUTP nick end labeling). Results: There were 15 cases of mucosa associated lymphoid tissue (MALT) lymphoma (9 in stomach, 6 in intestine) and 42 cases of diffuse large B cell lymphoma (DLBCL) (28 in stomach, 14 in intestine) in all the 57 cases of primary gastrointestinal BCL. The average apoptotic indexes (AI) were 0.16%, 2.54% in MALT lymphoma and DLBCL respectively. The average proliferation indexes (PI) were 2.22% and 8.71%,respectively. The p53 positive rates were 6.7% and 35.7%. PI ( P =0.026) and p53 ( P =0.044) had significant differences; But Bcl 2 positive rates were 60.0% and 35.7%,and HP positive rates were 66.7% and 23.8%, respectively. HP had significant differences ( P =0.005). Conclusion: HP and gastrointestinal MALT lymphoma had significant relation. Apoptosis and proliferative activity were higher in DLBCL than in MALT. The higher Bcl 2 expression in MALT may be related to lower apoptosis. p53 promotes apoptosis and p53 gene mutation may play a role in the progression from MALT to DLBCL. HP antibody may be used in HP detection in gastrointestinal BCL.
