Combined with the five Zang Yin-Yang theory, to discuss the spinal marrow and cerebral Yin Yang state. As the internal organs, we believe that the spinal marrow and cerebral are substantial Yin and functional Yang. Further we can diagnose and treat the cerebral and spinal marrow injury related diseases. In the clinical therapy of acute and chronic cerebral and spinal marrow diseases, we should maintain the substantial Yin by avoiding injury, preventing spinal degeneration and maintaining the blood supply; and we should adjusting the functional Yang by nourishing the blood and promoting blood circulation, calming the liver to stop the wind, keep Yin and Weiqi in balance, tonifying the spleen and kidney etc. From the author's experience ,the patient with acute cerebral and spinal marrow injury diseases should be treated by regulating lung, liver, spleen and kidney to remove the wet water and purge the fire;the patient with chronic cerebral and spinal marrow injury diseases should be treated by regulating heart, liver, spleen and kidney to enhance Yang and nourish Yin.

Objective To investigate the changes of serum concentration of amylase(AMY) and pathological of pancreas in severe acute pancreatitis of SD-rats treated with Ulinastatin combined with qingyitang and to provide the basis for clinical application.Methods Ninty male SD-rats with average weight of(271.59±11.13) g were conventional feeding for a week.Twelve hours before experiment,they were forbidden to take food.They were randomly divided into five groups(with 18 in every group):sham operation group,severe acute pancreatitis group,Ulinastatin treated group,qingyitang treated group,Ulinastatin combined with qingyitang treated group.Then eighteen rats in every group were divided randomly into 6 h,12 h and 24 h groups with six rats in each group.Severe acute pancreatitis model was created by retrograde injection of 5％ sodium taurocholate (0.1 ml/100 g) through pancreatic duct,in sham operation group,only pancreas were flipped.The three treated groups were treated with vein injection of Ulinastatin(20 000 U/kg)or qingyitang perfusion(1 ml/100 g)or Ulinastatin combined with qingyitangat 0 h,5 h and 11 h after severe acute pancreatitis model successfully created.AMY and patholigical changes of pancreas were measured.Results There was significant difference on AMY level at 6 h,12 h and 24.h between severe acute pancreatitis group and sham operation group[6 h:(16 518±327)U/L vs(1671±175)U/L,F =3296.24,P ＜0.01;12 h:(16 796±338) U/L vs(1751±223)U/L,F =3802.44,P ＜0.01;24 h:(1554±373) U/L vs(1724±187) U/L,F =2382.54,P ＜0.01].Compared with severe acute pancreatitis group,the AMY level and pathologic score both decreased significantly in Ulinastatin treated group,qingyitang treated group and Ulinastatin combined with qingyitang treated group(P ＜0.05 or P ＜ 0.01).At the same time,the AMY level and pathologic score both decreased more in Ulinastatin combined with qingyitang treated group than Ulinastatin treated group and qingyitang treated group(P ＜0.05 or P ＜ 0.01).Conclusion Combination of Ulinastatin with qingyitang in treatment of severe acute pancreatitis of rats is superior to treatment with single medicine.

Objective To investigate the effects on self-renewal of pancreatic cancer stem cells by inhibiting hedgehog signaling pathway through cyclopamine. Methods PANC1 stem cells, PANC1 adherent cells and immortalized pancreatic ductal epithelial H6C7 cells were treated with 0.5, 1, 2, 5, 10 mol/L of cyclopamine for 24, 48, 72 h. The expression of Smo mRNA and Gli1 mRNA were detected by real-time PCR.Cell growth viability was measured by CCK 8. Cell cycle and apoptosis were determined by flow cytometry.Results Seventy-two hours after cyclopamine treatment, the Smo mRNA expressions of PANC1 stem cells,PANC1 adherent cells and H6C7 cells were 1,0.83 and 2.61; the expressions of Gli mRNA were 57.27,26.35,1; the inhibitory rates were ( 37.85 ± 13.69 ) %, ( 8.53 ± 4.43 ) %, (43.55 ± 28.98 ) %. Compared with PANC1, the expressions of Smo mRNA, Gli1 mRNA and the inhibitory rate of PANC1 stem cells significantly increased ( P ＜ 0.05 ). The proportion of G1 stage of PANC1 stem cells significantly decreased from (67.41 ±6.35)% to (36.53 ±6.03)% (P ＜0.05), and the apoptosis decreased from (10.95 ±5.68) % to ( 5.73 ± 1.42 ) % ( P ＞ 0.05 ). The proportion of G1 stage of PANC1 cells significantly decreased from ( 67.64 ± 6.88 ) % to ( 53.13 ± 1.10 ) % ( P ＜ 0.05 ); the apoptosis decreased from ( 12.08 ±4.12)% to (5.66 ± 1.33)% (P ＞0.05). While both the proportion of G1 stage and apoptosis of H6C7 cells was not significantly different. Conclusions Cyclopamine can inhibit the proliferation of PANC1 stem cells via blocking hedgehog signal pathway, and the mechanism may not be associated with cell apoptosis.

Objective To establish the method of suspension culture for stem cells from human pancreatic cancer cell line PANC1.Methods PANC1 cells were cultured in serum-free medium under floating-culture system.Tumor cell spheres were observed by optical microscope.Expression of CD133 and cell cycle were detected by flow cytometry.Cancer stem cells were induced to differentiate with 10%FBS,and expression of CK18,was evaluated with immunofluorescence microscope.Spheres cells were injected into the subcutaneous space of NOD/SCID rat and tumor formation was monitored weekly.Results PANC1 cells could form the stem cells spheres,and the rate of sphere formation was stable between 4%0 and 5%0 after 20 passages in vitro.The expression of CD133(5.91±0.7%)and proportion of G0/G1 phase cell(80.99±2.60%)was significantly increased in spheres cells compared with parental PANC1 cells(1.44±0.52%and 69.01±5.03%),and the difference was statistically significant(P＜0.05).When these spheres cells were cultured in media with serum,these cells gradually returned to the status of parental cells and expressed CK18,2×103 sphere cells injection could initiate tumor fornmtion in NOD/SCID rat.Conclusions Tumor spheres stem cellscould be generated under serum-free floating-culture system.The sphere cells possessed the capacities of self renew,difierentiation,and tumorigenic potential.

OBJECTIVE:To investigate the effects of simvastatin intensive treatment on the Postoperative Related Indexes of patients with acute coronary syndrome(ACS) underwent percutaneous coronary intervention(PCI). METHODS:106 patients with were included in the study and randomly divided into observation group(53 cases)and control group(53 cases). Both groups were given aspirin 100 mg,qd+clopidogrel 75 mg,qd before PCI for 4 weeks;observation group was additionally given Simvastatin tablet orally 20 mg before supper 15 d before surgery. TC,TG,LDL-C,HDL-C,hs-CRP,IL-6 and IL-18 levels,LVEF,the occurrence of coronary artery restenosis were detected in 2 groups before surgery and 6 months after surgery. The occurrence of ADR was recorded during treatment. RESULTS:There was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between 2 groups before surgery and 6 months after surgery (P>0.05). There was no statistical significance in hs-CRP,IL-18, IL-6 and LVEF levels between 2 groups before surgery(P>0.05). 6 months after surgery,hs-CRP,IL-6,IL-18 and LVEF levels of 2 groups were significantly higher than before treatment;hs-CRP,IL-6 and IL-18 levels of observation group were significantly lower than those of control group,and LVEF was significantly higher than control group,with statistical significance (P<0.05). The incidence of coronary artery restenosis in observation group was significantly lower than control group, with statistical significance (P<0.05). No ADR was found in 2 groups during treatment. CONCLUSIONS:Preoperative simvastatin intensive treatment can effectively reduce cardiovascular inflammation degree in patients with ACS after PCI,prevent the formation of coronary artery thrombus,and reduce the incidence of coronary artery restenosis so as to effectively improve the prognosis and don' t increase the incidence of ADR.

In a fusion of BABL/C murine spleen cells immunizated with human fetal thymocytes and P_3X_(3)Ag_(,3), myeloma cells, six monoclonal antibodies(McAb) were produced. They were termed HIT_1. HIT_2. HIT_3. HIT_4.HIT_(6-1) and HIT_(6-2), respectively. The specificity of these McAbs were analysed by indirect immunofluorescence technique and FACS.Results showed that they reacted with 80～90%thymocytes,but hardly with peripheral blood mononuclear cells and spleen cells in adults,and nonreactive with red blood cells, granulocytes and platelets, According to their reaction with the tonsil cells, we can divide these six McAbs into three groups: Groupl including HIT_1, HIT_2, and HIT_(?) McAbs reacted approximately with 1/3 tonsil cells; basically GroupⅡ including HIT_(6-1) and HIT_(6-2) McAbs gave negative reaction with tonsil cells; GroupⅢ McAb HIT_4 reacted with 15% tonsil cells, which suggested these were a heterogeneous group McAbs with different specificities. In comparision with OKT series of McAbs in thymus, peripheral blood and tonsil, HIT_(1-3) are similar to OKT_(10) and,HTT6-l and HIT_(6-2) are just like OKT_6,but HIT_4 seems to be a new McAb different frOm HIT_(1-3) and HIT_(6-1) HII_(6-2). The competitive binding assay showed that HIT_(6-1) and HIT_(6-2) labeled with FITC can be inhibited by unlabeled HIT_(6-1) and HIT_(6-2) each other and can also be blocked by OKT_6, suggesting further these antibodies recognized a same epitope on thymocytes. Cross reaction were also demonstrated on HIT_1, and HIT_2 but not on HIT_3, suggesting HIT_1 and HIT_2 recognized the same determinant and HIT_3 recognized another. So six antibodies are McAbs against T cell differentiation antigens.They are useful for research the differentiation of T cells and the classification of malignant lymphadenosis diseases.

Objective:To evaluate the correlation between the timed up and go(TUG)test and fall risks in elderly frail patients.Methods:From July to September 2019, elderly frail patients who were treated at the cardiovascular department of our hospital were enrolled.Basic clinical data and fall-related information of patients were collected.Patients were divided into the fall group and the non-fall group.Results on the body mass index(BMI), TUG, 4-meter maximum walking speed(4 m MWS)and Barthel index were compared between the two groups.The correlation between TUG and each indicator was examined.Multivariate Logistic regression analysis was used to analyze the correlation between the TUG and falls in elderly patients.Results:A total of 96 eligible patients were enrolled, including 35 in the fall group and 61 in the non-fall group.The average TUG time was longer in the fall group than in the non-fall group(16.45±6.44 s vs.10.17±2.91 s, t=-6.556, P<0.001). The correlation analysis results showed that the TUG was correlated with falls and 4 m MWS( r=0.582 and 0.875, both P<0.001). Multivariate Logistic regression analysis showed that the TUG( OR=1.201, 95% CI: 1.111-1.470, P=0.004)and 4 m MWS( OR=1.146, 95% CI: 1.063-1.244, P=0.015)were risk factors for falls. Conclusions:The TUG is correlated with fall risks in elderly frail patients and should be recommended as a routine test in clinical practice.

Objective: To investigate the clinical features and prognosis factors of acquired immunodeficiency syndrome (AIDS) patients complicated with cryptococcal meningitis (CM). Methods: Retrospective analyses were performed on clinical features, laboratory data, treatment status and related prognosis factors in 81 AIDS patients with CM admitted to the Department of Infectious Diseases, Beijing You′an Hospital, Capital Medical University from January 2010 to December 2017. The t test, rank sum test and χ² test were employed to analyze the data. Results: Of the 81 AIDS patients with CM, 71 cases were infected with human immunodeficiency virus (HIV) by sexual transmission (87.7%). The most common clinical symptoms were fever in 60 (74.1%), headache in 72 (88.9%), and nausea and vomiting in 56 (69.1%). Cerebrospinal fluid (CSF) examination results show that 60 cases (74.1%) had elevated opening pressure, the white blood cell count was 17.0 (6.0, 44.5)×10⁶/L, monocyte count was 9.0 (3.0, 29.5)×10⁶/L, the level of chloride was (117.26±5.61) mmol/L, of glucose was 2.89 (2.05, 3.41) mmol/L, of protein was 0.32 (0.21, 0.65) g/L, ink staining positive rate was 84.0% (68/81), fungal culture positive rate was 59.3% (48/81). The positive rate of serum cryptococcal antigen was 96.3% (78/81), and CSF cryptococcal antigen positive rate was 93.8% (76/81). The clinical efficacies were not significant different among different treatment regimens (χ²=1.479, P=0.533). After treatment, 60 patients survived and 21 died, with an overall mortality rate of 25.9%. Univariate analysis showed that consciousness disorder and CSF opening pressure were significantly higher in the death group than those in the survival group (χ²=22.365, t=0.317, respectively, both P<0.05), while serum albumin (Alb) and CD4⁺ T lymphocyte counts were significantly lower in the death group than those in the survival group (t=7.975, Z=-3.073, respectively, both P<0.05). Multivariate logistic regression analysis showed that consciousness disorder and Alb were independent factors influencing the clinical outcome of AIDS patients with CM. Consciousness disorder was related with poor outcome (odd ratio (OR)=26.704, P=0.011, 95% confidence interval (CI) 2.115-337.247), and higher Alb was related with good outcome (OR=0.671, P=0.005, 95%CI 0.507-0.888). The area under the receiver operating characteristic curve of serum Alb for predicting poor outcomes of AIDS patients with CM was 0.932 (95% CI 0.859-0.998, P<0.01). By using 31.7 g/L as cut-off value, the sensitivity was 95% and the specificity was 81% for predicting poor outcome. Conclusions AIDS complicated with CM has a high mortality rate, and its clinical features are lack of specificity. Consciousness disorder and Alb are independent prognosis factors.
