To discuss the feasibility of the pharmacodynamic evaluation method for traditional Chinese medicine (TCM) formula particles, with traditional decoction for reference and the intervention of Magnoliae Officinalis Cortex in rats with ulcerative colitis (UC). First of all, the similarity of traditional Magnoliae Officinalis Cortex decoction and formula particles of different manufacturers was defined by using the IR fingerprint. The UC rat model was established and given Houpo formula particles of different doses and manufacturers, with the decoction for reference, in order to observe disease activity index (DAI), colon mucosa damage index (CMDI), pathologic changes, nitric oxide (NO), endothdin (ET), substance P, vasoactive intestinal peptide (VIP). Their intervention effects on UC rats were compared to study the difference between Sanjiu and Tianjiang Houpo formula particles, in order to demonstrate the feasibility of the pharmacodynamic evaluation method for Houpo formula particles. According to the results, Houpo formula particles showed similar pharmacodynamic actions with the traditional decoction. The pharmacodynamic comparison of Houpo formula particles of different manufacturers showed no statistical significance. The experiment showed that on the basis of the TCM compounds, a prescription dismantlement study was conducted to define target points of various drugs. The traditional decoction was selected for reference in the comparison of corresponding formula particles for their pharmacodynamic equivalence. This method could avoid controversies about single or combined boiling of formula particles, and give objective comments on the pharmacodynamic effect of the formula particles. The method is proved to be feasible.

Objective To explore the relationship between blood lipid level and primary open angle glaucoma(POAG)and intraocular pressure(IOP).Methods A retrospective case-control study was designed.80 POAG patients from EYE & ENT hospital of FUDAN university were collected as a case group from January 2015 to May 2016.Meanwhile 80 age and gender matched healthy people were collected as a control group.The differences of gender in men subgroup (POAG:44,Control:39) and female subgroup (POAG:36,Control:41) showed no statistic significance.Serum total cholesterol(TC),total triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),apolipoprotein A(Apo A) and apolipoprotein B(Apo B) were measured using Roche automatic biochemical analyzer.The analysis of the above mentioned lipid levels between POAG group and control group was conducted by independent student′s T test and multivariate logistic regression.The relationship between lipid level and IOP was analysied using Pearson correlation test.Results The TG level was (1.40±0.71)mmol/L in the POAG group,(1.00±0.37)mmol/L in the control group.The difference had statistic significance (t=4.467,P<0.001).The HDL-C level in the POAG group was (1.22±0.36)mmol/L,(1.38±0.25)mmol/L in the control group.The difference also had statistic significance (t=-3.228,P=0.002).Comparison between the men subgroup and female subgroup found that the TG level in the POAG group of men was (1.47±0.71)mmol/L,(1.01±0.36) mmol/L in the control group and the HDL-C level were (1.14±0.31) mmol/L,(1.32±0.20)mmol/L in two groups.Both the level of TG and HDL-C had statistic significance in men (t=3.717,P<0.001;t=-3.240,P=0.002).The TC,TG level in the POAG group and control group of women respectively were (4.59±0.81)mmol/L,(1.33±0.72)mmol/L and (4.21±0.64)mmol/L,(0.99±0.38)mmol/L.Both blood level were significantly higher than the control group in women (t=2.278,P=0.026;t=2.503,P=0.016).Logistic regression analysis showed that the TG level correlated with POAG (P=0.004,OR=2.831,95% CI=1.392-5.759)and both POAG in the men and women (P=0.025,OR=3.223,95% CI=1.156-8.989;P=0.045,OR=2.554,95% CI=1.020-6.395).Pearson test showed that the TG level of POAG patients was positively associated with IOP in spite of gender(P<0.05).Conclusion The peripheral blood level of TG was significantly increased in the POAG patients and significantly correlated with IOP,which indicated that the increased peripheral blood level of TG may be the independent risk factor for the POAG..

Objective A large sample of multi-factor Logistic analysis of clinical biochemical indicators from elderly cataract patients were done to find the characteristics of possible changes in potential factors for cataract-related indicators and explore the pathogenesis of cataract from the perspective of laboratory diagnosis.Methods A retrospective case control study was conducted .Cataract patients from Eye-Ear Nose Throat Hospital of Fudan University were collected during June 2011 to July 2015 and routinely tested for 14 clinical biochemistry indicators including ALB , GLU, TP, GLB, BUN, URCA, Cr, LDH, ALP, Ca, Na, K, Cl, and P.The mean age of the 3 527 cataract patients (1 804 males, 1 723 females) was (64.47 ±11.29) years.Those data were reserved by LIS (Laboratory Information System) system and were retrieved for large data analysis . The control group was filtered from hospitalized patients besides cataract patients during January 2014 to July 2015.The mean age of the 3 333 control subjects ( 1 770 males, 1 563 females ) was ( 64.04 ±9.03 ) years.Biochemical indicators between cataract group and control group were analyzed by independent student′s t-test and Logistic regression .Meanwhile , the objects were divided into 3 groups according to the age (40-59 years,60-79 years,≥80 years) for independent student′s t-test with the control group respectively .Results There are no statistical difference in age ( t=1.663,P=0.096) and gender ( t=2.63,P=0.105 0) between cataract group and control group ( P>0.05).The results of Logistic regression between cataract group and control group were as follow : ALB (OR=1.053,95%CI=1.019-1.088),BUN(OR=1.113,95% CI=1.076-1.152),Cr(OR=1.007, 95%CI=1.003-1.010),GLB(OR=1.049,95% CI=1.018 -1.081),GLU(OR=1.175,95% CI=1.139-1.211),Cl(OR=1.059,1.032 -1.088),Na(OR=1.180,95% CI =1.150 -1.212).Those might be enrolled as risk factors for cataract (P<0.05).The level of ALB, GLU, Na and Cl in cataract group according to different age groups were significantly higher ( t=8.780,t=4.670, t=9.695, t=6.415, P<0.05) than that of control in 40-59 age group;the level of ALB, BUN, Cr, GLU, Na and Cl in cataract group was significantly higher ( t=4.974, t=9.414, t=4.123, t=6.906, t=14.741, t=9.212, P<0.05) than control in 60 -79 age group; the level of BUN, Cr, GLU, Na and Cl in cataract group was significantly higher (t=6.077, t=4.906, t=2.626, t=5.459, t=3.424, P<0.05) than control in 80-age group.Conclusions The level of ALB, BUN, GLB, Cr, GLU, Na and Cl in peripheral blood of cataract patients was significantly increased which suggested that those change might associated with the pathogenesis of cataract .

TCM believes that physical tendons and bone are interdependent, keeping dynamic balance, and they influence each other pathologically. Physical tendons and bone balance is human spine physiological state. Physical tendons and bone imbalance is the important pathogenesis of spine and related diseases. The core of physical tendons and bone balance-regulating theory is the physique homology and syndrome differentiation and treatment. This article expounded from the above aspects in details.

Objective To explore the effects of bilirubin on myeloid differentiation factor phospho-p38 mitogen-activated protein kinase (p-p38MAPK) and apoptosis in splenocytes of neonatal rats.Methods Seven-day-old Sprague Dawley rats (clean grade),male or female,weighting 12.0-15.0 g,were randomly assigned to 6 groups.There were blank control group (Ⅰ),lipopolysaccharide (LPS) control group (Ⅱ),15 mg/kg bilirubin control (free-LPS) group (Ⅲ),15 mg/kg group (Ⅳa),30 mg/kg group (Ⅳb) and 50 mg/kg group (Ⅳc),and then subsequently divided into 2 h,5 h and 24 h subgroups in each groups.Some of the 200 newborn rats died amid the experiment,tinally,a total of 144 cases were involved in the analysis of results,and 8 rats in each subgroups.Newborn Sprague Dawley rats were administered at various doses of bilirubin (15 mg/kg,30 mg/kg and 50 mg/kg,respectively) intravenously; 1 h after injection,the rats were administered LPS intraperitoneally at a dose of 1 mg/kg;p-p38MAPK were detected by immunohistochemistry;Apoptosis in splenocytes was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling methods at 2 h 5 h and 24 h after the injection of bilirubin.Results 1.Expression of p-p38MAPK in each group:bilirubin in low-mid concentrations of range inhibited LPS-induced p38MAPK activation (qⅣa =20.93,10.37,respectively at 2 h,and 5 h,all P ＜ 0.01 ;qⅣ b =79.97,14.79,all P ＜ 0.01).The inhibition strengthened with increasing concentration of bilirubin.The effect was observed at 2 h,strengthened at 5 h,disappeared at 24 h.Bilirubin in the high concentrations of range stimulated the expression of p-p38MAPK (qⅣc =32.55,19.23,27.72,respectively at 2 h,5 h and 24 h,all P ＜0.01),observed at 5 h,reduced at 24 h.2.Effects of bilirubin on apoptosis in splenocytes:LPS could increased the apoptosis index (AI) of splenocytes(q =54.62,P ＜ 0.01);The AI of splenocytes had no significant change in low concentrations of range of bilirubin (q =43.92,P ＞ 0.05).Low-mid concentration of bilirubin with LPS reduced the AI of splenocytes (q Ⅳ a =4.48,P ＜ 0.01 ;q Ⅳ b =2.07,P ＜ 0.05),while high concentration of bilirubin with LPS increased the AI of splenocytes (q =5.08,P ＜ 0.01).Conclusions Bilirubin in low-mid concentrations of range could inhibit the expression of LPS-induced p38MAPK,while bilirubin in high concentrations of range stimulated the expression.As the concentration of bilirubin elevated,its inhibition was prolonged.Bilirubin in high concentrations of range bilirubin could induce apoptosis in splenocytes.The immune dysfunction in neonatal hyperbilirubinemia may have something to do with the regulation of phosphorylation of p38MAPK and activation of apoptotic pathways.

Objective To observe the changes of endothelin-1 (ET-1) and prostaglandin E2 (PGE2) in exhaled breath condensate (EBC) and serum of patients with acute respiratory distress syndrome (ARDS) after treated by Qingfeitang and investigate its clinical value. Methods 52 ARDS patients receiving mechanical ventilation at intensive care unit (ICU) were divided into the Qingfeitang treatment group and the control group, with 26 cases in each group. The EBC were collected by Ecoscreen condenser within 24 h after diagnosis of ARDS and on the 5th day of medication, and the venous blood were collected at the same time. The levels of ET-1 and PGE2 in the EBC and serum of different period were measured by EIA. Results (1) After treatment, The levels of ET-1 in EBC and serum of the Qingfeitang treatment group were significantly lower than those of the control group. (2) After treatment, the levels of PGE2 in serum of the Qingfeitang treatment group were significantly lower than that of the control group. (3) The oxygenation index difference before and after treatment of Qingfeitang in the treatment group was higher than in the control group. (4) The duration of mechanical ventilation of the Qingfeitang treatment group was significantly less than that of the control group. Conclusions Qingfeitang could be an effective method for alleviating acute respiratory distress syndrome.

To observe whether plasma levels of lysophosphatidic acid (LPA) can be decreased in patients with cerebrovascular diseases after the treatment with aspirin. Methods:A total of 1,400 patients were recruited. Among them,803 patients were diagnosed as probable ischemic stroke,and 343 patients were diagnosed as ischemic stroke. Thirty-four health volunteers were used as control subjects. The levels of LPA were measured by chromatography with the combination of inorganic phosphorus quantitative method. Results: The levels of LPA in the ischemic cerebrovascular group (3.11 ± 1.55 μmol/L) were significantly higher than those in the control group (1.77 ± 1.04 μmol/L) (P < 0.001). Taking aspirin (80 mg,qd) for one month significantly decreased the levels of LPA. After stopping aspirin for one month,the level of LPA re-elevated (3.90 ± 1.09 μmol/L),was higher than that during administration of aspirin (1.93 ±0.85 μmol/L(P <0.001). Conclusions: There are close correlations between the increased levels of LPA and the platelet activation. Aspirin decreases the level of plasma LPA;this may be one of the mechanisms of aspirin in prevention against ischemic stroke.

ObjectiveTo investigate the serum prostate-specific antigen (tPSA),serum free PSA to total PSA ratio (f/tPSA),prostate volume (PV) and prostate-specific antigen density (PSAD) in early prostate cancer (PCa) diagnosis.MethodsRetrospective analysis was performed on serum PSA values and related test results from 252 cases of BPH patients and 49 patients with PCa.Prostate volume (PV) was measured by transrectal ultrasound (TRUS),and the f/tPSAand PSAD values were calculated.The differences of serum tPSA,f/tPSA,PV,and PSAD between BPH and PCa group were compared,the area under the ROC curve was used to evaluate these four indicators for its diagnostic sensitivity and diagnostic specificity.ResultsThe values of tPSA,PSAD in PCa group were significantly higher than BPH group ( P ＜0.05),while the values of f/tPSA,PV in PCa group were significantly lower than BPH group ( P ＜0.01orP ＜0.05).The ROC area showed that serum tPSA(0.8013),f/tPSA(0.7390),PV(0.5613) had lower diagnosis value than PSAD(0.9214) in early prostate cancer ( PSAD ＞ tPSA ＞ f/tPSA ＞ PV).When the upper limit of normal PSA was set to take 4ng/ml,the sensitivity was 91.49％,diagnostic specificity was 51.05％.When the f/tPSA threshold set to 0.16,the diagnostic sensitivity was 57.78％,diagnostic specificity was 78.72％.When PSAD threshold was set to 0.15,diagnostic sensitivity was 88.24％,diagnostic specificity was 81.52％.ConclusionsPSA,f/tPSA and PSAD are indicators for biopsy or followup in early diagnosis of prostate cancer.In particular,the diagnostic value of PSAD has higher sensitivity and specificity than PSA and f/tPSA in the diagnosis of prostate cancer.
