BACKGROUND: Cerebral infarction is commonly associated with blood stasis syndrome. Abnormal alternation of blood rheology is generally manifested as increased blood viscosity and hematocrit (HCT). In isometric hemodilution, a certain amount of red blood cell (RBC) is shifted by bleeding and simultaneously, isometric diluter is supplemented to reduce whole blood viscosity.OBJECTIVE: To observe the improvement of astragalus injection, the Chinese herb for qi tonification and isometric hemodilution on blood rheology in blood stasis syndrome of cerebral infarction.DESIGN: Randomized controlled experiment and case-control analysis were designed.SETTING: Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. PARTICIPANTS: In cerebral infarction group (infarction group), 64 inpatients of senile ischemic cerebral vascular disease were collected from Union Hospital Affiliated to Huazhong University of Science and Technology from March 2002 to March 2004. Al l of cases were aged over 60 years and were in conformity with the diagnostic criteria on blood stasis syndrome. According to random number table, routine treatment group (routine group) and the group of integrative therapy of Chinese and western medicine (experimental group) were divided, 32 cases in each one. 47 healthy people of similar age and diagnosed with routine physical examination were selected in normal control. METHODS: In routine group, cerebral infarction was treated with routine therapy, including extending capacity, reducing viscosity, resisting coagulation, blocking aggregation of platelet and dehydration and general symp tomatic supporting treatment. In experimental group, on basis of routine treatment, isometric hemodilution and astragalus injection, the Chinese herb for qi tonification were used. 10% of total blood amount (about 450-650 mL) was collected from vein, and colloid solution of same volume was injected intravenously. The treatment was applied once every 5 days, continuously for 3 times. Astragalus injection 50 mL mixed with physical saline 250 mL was intravenous dropped, once per day, continuously for 3 weeks. MAIN OUTCOME MEASURES: ① Comparison of indexes in bloodrheology before and after treatment in routine group and experimental group. ② Comparison of indexes in blood rheology between normal control and infarction group. RESULTS: According to intention management, 64 patients and 47 normal persons all entered result analysis. ① Comparison between infarction group and normal control: RVB, HCT and PFC (fibrinogen) were higher than normal control [(3.90±0.73), (3.40±0.28) mPa·s; (46.39±6.03) %,(42.61±2.91)%; (3.25±0.75), (3.08±0.46) g/L, P < 0.01, 0.05], MTIE (de formity index of RBC) was lower than normal control (0.958±0.006, 0.961 Shen H,Lu YD.Study on quantitative messurement of immunohistochemical ±0.004, P < 0.05). ② Comparison between routine group and experimental group: Difference in some indexes presented before the treatment. After treatment, RVB, HCT and PFC in experimental grou p were all lower than routine group [(3.90±0.52), (4.21±0.68) mPa·s; (43.80±3.29)%, (48.47±4.50)%; (3.31±0.60), (3.68±0.67) g/L, P < 0.01, 0.05]. CONCLUSION: Isometric hemodilution therapy and astragalus injection reduces blood viscosity, improves blood rheology and alleviates clinical svmptoms of blood stasis syndrome in senile cerebral infarction.

Objective To investigate the role of tissue-resident memory T lymphocytes in the pathogenesis of psoriasis.Methods Clinical information was collected from 32 patients with progressive plaque psoriasis.Tissue specimens were obtained from both lesional and nonlesional psoriatic skin of all the patients,as well as from faded lesions in 9 of these patients.Tissue specimens from the normal skin of 10 healthy individuals served as the controls.Immunohistochemical staining was performed to detect the two characteristic surface markers CD69 and CDI03 on tissue-resident memory T lymphocytes and to analyze the status of these T lymphocytes at different stages of psoriasis.The results of immunohistochemical staining were compared by t test.Results The mean number of CD69+CD103+ T lymphocytes per high-power field was significantly higher in lesional skin than in nonlesional skin of the 32 patients (11.34 ± 7.60 vs.2.72 ± 4.20,t =8.46,P ＜ 0.01),but similar between psoriatic lesions in the 9 patients before and after subsidence (14.33 ± 2.21 vs.12.00 ± 4.58,t =1.98,P =0.08).There was no significant difference in the mean number of CD69+CD103+ T lymphocytes between nonlesional psoriatic skin and normal control skin (2.72 ± 4.20 vs.1.70 ± 2.98,t =0.71,P ＞ 0.05).Conclusion Tissue-resident memory T lymphocytes may play a role in the formation and recurrence of psoriatic lesions in patients.

Objective To investigate the relationship of CD4+ and CD8+ T cells with melanocytes in skin of patients with psoriasis,and to study their clinical significance.Methods Tissue specimens were obtained from both lesional and nonlesional skin of 29 patients with progressive psoriasis and 5 patients with regressive psoriasis,as well as from normal skin of 6 healthy individuals.Immunohistochemical staining was performed to determine the quantity and distribution of CD4+ T and CD8+ T cells,as well as the quantity of melanocytes and proportion of cells containing pigment granules in the basal layer of these specimens.Statistical analysis was carried out with the software SPSS 18.0 by one-way analysis of variance (ANOVA),least significant difference (LSD) test and Pearson correlation analysis.Results In patients with psoriasis,the mean number of CD4+ T cells per high-power (× 200) field was significantly larger in lesional skin than in nonlesional skin (epidermis:5.29 ± 4.66 vs.0,P＜ 0.05;dermis:77.50 ± 43.66 vs.9.67 ± 7.73,P＜ 0.05),so was the mean number of CD8+ T cells per high-power (× 200) field (epidermis:7.83 ± 6.27 vs.0.71 ± 1.20,P＜ 0.05;dermis:46.08 ± 34.26 vs.5.54 ± 4.43,P ＜ 0.05).A significant increase was also observed in the number of CD4+ and CD8+ T cells in lesional skin of patients with psoriasis compared with the normal control skin (both P ＜ 0.05).The lesional skin of patients with psoriasis also showed significandy increased number of melanocytes (103.45 ± 16.96),but decreased proportion of pigment granule-containing cells (7.45％ ± 3.86％) in the basal layer compared with nonlesional skin (43.62 ± 14.20,P＜ 0.05;43.10％ ± 14.91％,P＜ 0.05) and normal control skin (43.33 ± 14.02,P＜ 0.05;54.17％ ± 29.40％,P ＜ 0.05).There were no significant differences in either the mean number of CD4+ T cells,CD8+ T cells and melanocytes or the proportion of pigment granule-containing cells between nonlesional psoriatic skin and normal control skin (all P ＞ 0.05).The mean number of melanocytes was significantly higher in regressive psoriatic lesions than in white patches arising in subsided psoriatic lesions (P ＜ 0.05) and normal control skin (P ＜ 0.05),but similar between white patches and normal control skin (P ＞ 0.05),while the proportion of pigment granule-containing cells was insignificantly lower in regressive psoriatic lesions than in white patches (P ＞ 0.05),and significantly lower in regressive psoriatic lesions and white patches than in normal control skin (both P ＜ 0.05).Neither the number of CD4+ T cells nor that of CD8 + T cells was correlated with the number of melanocytes or the proportion of pigment granule-containing cells in progressive psoriatic lesions (both P ＞ 0.05),while the number of both CD4 + T cells and CD8 + T cells was positively correlated with that of melanocytes (r =0.46 and 0.56,respectively,both P ＜ 0.05),but uncorrelated with the proportion of pigment granule-containing cells in nonlesional psoriatic skin (both P ＞ 0.05).Conclusions In progressive psoriatic lesions,there is a significant increase in the number of CD4+ and CD8 + T cells as well as melanocytes in the basal layer,but a significant decrease in the proportion of pigment granule-containing cells.After subsidence of psoriatic lesions,both the number of melanocytes and proportion of pigment granule-containing cells gradually reach the levels in normal skin of healthy individuals.

To summarize the clinical characters of optic neuritis caused by antituberculosis drugs, and to discuss the prevention countermeasures.
● METHODS: The clinical characters of optic neuritis caused by antituberculosis drugs among those outpatients and ward patients from January 2003 to January 2013 were reviewed and analyzed.
● RESULTS: Optic neuritis caused by antituberculosis drugs was rare ( 17 / 60000 ), while retrobulbar neuritis was common. The drugs inducing optical neuritis were mainly ethambutol, followed by isoniazid and streptomycin. The vision of patients would have different degrees of improvement via the following treatment after specific diagnosis, i. e. , timely stopping the tuberculosis medicine associated with optic neuritis, and taking vitamin supplements, dilating blood vessels and applying hormone therapy according to the illness.
●CONCLUSlON: We should pay attention to the change of the vision of patients during the usage of antituberculosis drugs. ln the case of sudden eyesight deterioration, ophthalmology examination and timely treatment are advised preventing blindness.

Objective To investigate the correlations between the soluble form of B7-H3 ( sB7-H3) and the cytokines of IL-17 and IL-8 in serum samples from patients with primary hepatocellular carcino-ma ( HCC) and to evaluate their clinical values for early diagnosis of HCC.Methods Serum samples were collected from 63 patients with HCC and 50 healthy subjects.The expression of sB7-H3, IL-17 and IL-8 in serum samples were detected by ELISA.Receiver operating characteristic ( ROC) curve was generated to an-alyze the diagnostic values of sB7-H3, IL-17 and IL-8 for hepatoma.The logistic regression model was used to predict the probability of hepatoma by using sB7-H3, IL-17 and IL-8 in combination.Results The levels of sB7-H3, IL-17 and IL-8 in serum samples collected from the patients with HCC were significantly higher than those from healthy subjects.A positive correlation was found between the levels of sB7-H3 and IL-17 in serum samples from patients with HCC.No correlation was found between sB7-H3 and IL-8.A negative cor-relation was found between the levels of IL-17 and IL-8 in serum samples from patients with HCC.ROC curve analysis showed that the area under the curve (AUC) of sB7-H3, IL-17 and IL-8 were 0.832, 0.657 and 0.953, respectively, indicating the statistical significance of them for the diagnosis of HCC.The logistic regression showed that the AUC, diagnostic sensitivity and specificity of the regression model PRE in the pre-diction of HCC were 0.960, 91.30% and 94.29%, respectively, which was much better than using the three indicators alone.Conclusion The levels of sB7-H3 were positively correlated to the levels of IL-17 in serum samples from patient with HCC.The logistic regression model of combination of sB7-H3, IL-17 and IL-8 obtained in this study could be used for early clinical diagnosis of HCC in the future.

Objective To investigate the real-time regulatory effects of IFN-γ, programed death ligand 2(PDL2) and janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway on the adherence, proliferation and migration of human placenta-derived mesenchymal stem cells(hPMSCs) based on a finding that IFN-γ could enhance the expression of PDL2 in hPMSCs through JAK/STAT signaling pathway.Methods hPMSCs were isolated by using enzyme digestion method and then co-cultured with IFN-γ, anti-PDL2 monoclonal antibody (anti-PDL2 McAb) and JAK inhibitor, respectively.Real-time cell analysis (RTCA) was used to detect the dynamic changes in the adherence, proliferation and migration of hPMSCs following various interventions.Results IFN-γ remarkably suppressed hPMSCs proliferation during the period from 40 hours to 80 hours after intervention and also inhibited the non-targeted migration of hPMSCs.However, hPMSCs adherence was not affected by IFN-γ.Co-culturing hPMSCs with anti-PDL2 McAb significantly enhanced hPMSCs adhesion and inhibited their non-targeted migration, but had no significant effect on hPMSCs proliferation.Furthermore, the proliferation of hPMSCs co-cultured with IFN-γ and anti-PDL2 McAb was significantly inhibited as compared with that of anti-PDL2McAb treatment group.The adhesion, migration and proliferation of hPMSCs were significantly inhibited after co-culturing them with JAK inhibitor.Conclusion IFN-γ can remarkably suppress the proliferation and migration of hPMSCs.PDL2 can enhance the migration and inhibit the adhesion of hPMSCs.JAK/STAT signaling pathway is involved in regulating the adhesion, migration and proliferation of hPMSCs.

The blood reserve bank for preparedness against war,as a store of blood products and a base of blood supply,bears the responsibility of wartime emergency blood supply.Site selection is the basis of the construction of the blood reserve bank and directly related with its capacity of blood supply in both peace and wartime.The decision-making process concerning site selection is complicated and multi-aimed with various factors mutually related and conditioned.This paper proposes some basic principles of selecting the site of the blood reserve bank for preparedness against war,which are hoped to be beneficial for the demonstration of its site selection.

Objective To observe the effect of fleabane injection on serum level of D-dimer, fibrinogen and hypersensitive C-reactive protein in patients with IgA nephropathy and to explore the mechanism of fleabane injection for treating IgA nephropathy. Methods 29 patients with IgA nephropathy were given fleabane injection together with routine treatment. Another group of 28 patients with IgA nephropathy were only treated with routine treatment as con-trol. Determinations of 24 hours urine protein output(24HPQ), serum level of D-dimer(D-D), Fibrinogen(Fib) and hypersensitive C-reactive protein (hsCRP) were carried out pre- and post-study. Results Significant decrease in 24HPQ , serum level of D-D, Fib and hsCRP were observed in both treatment group and control group(P <0. 01 ～0. 05), but more significant in treatment group as compared with control group ( P < 0. 05). Conclusion Flea-bane Injection plus routine treatment could significantly decrease 24HPQ in patients with IgA nephropathy, and this maybe contribute to regulation of D-D, Fib and hsCRP by fleabane injection.

Objective To analyze the clinical features of patients with cholelithiasis treated in our hospital in the recent 10 years to explore the changing tendency of the spectrum of cholelithiasis in the Jiaodong region. Methods The clinical data of 2899 patients receiving operation for cholelithiasis in this hospital between January 1998 and January 2008 were retrospectively analyzed. The clinical parameters of sex, age and the lesion sites were reviewed. Compared with the clinical data of cholelithiasis patients in 1991, the data of the 2899 patients were statistically analyzed by SPSS 12.0 package.Results Significant differences existed in sex, e peak morbidity, and lesion sites. The ratio of male patients and female patients with cholelithiasis in differents site had obvious diversity. The constituent ratio of the female was manifestly higher than that of the male. The peak morbidity age range of cholecystolithiasis was 40 to 69. The peak age of gallbladder stones combined with common bile duct stones was 70 to 79, which was the same as that of common bile duct stones. The peak age of intrahepatic bile duct stones was 40 to 59. The constituent ratio of cholecystolithiasis was obviously higher than cholelithiasis in other sites. The incidence of cholecystolithiasis increased with age. Conclusion In the recent 10 years, female's ratio of gallbladder stones and intrahepatic stones was higher than male's.The morbidity of cholelithiasis significantly increased in aged patients. The spectrum of cholelithiasis has changed significantly.
