Up to now, advantages and disadvantages in the treatment of hypertensive middle_ and large_amount cerebral hemorrhage (HMLCH) by western medicine or traditional Chinese medicine,or by medical treatment or surgical treatment still exist. Mortality and disablement rate remain high. Western medicine combined with Chinese herbal medicine shows better effect in treating HMLCH, but the related research is preliminary. Therefore, thoughts of establishing comprehensive therapeutic protocols for HMLCH are presented as follows. Western medicine combined with Chinese herbal medicine is the fundamental therapeutic principle. Proper surgical operation should be employed promptly to clear away hemotoma and relieve the symptoms first according to the situation of the patient, hospital and the surgeon. Clearing heat and calming the liver, removing blood stasis and phlegm, relaxing the bowels and restoring consciousness are the fundamental therapeutic methods for HMLCH with yang_excess syndrome, and reinforcing Qi and activating blood circulation, removing phlegm and dredging channels, relaxing the bowels and restoring consciousness for yin_excess syndrome. Routine treatment and symptomatic treatment also should be taken into account.

Objective To investigate the changes of human epidermal stem cells after transfected with human telomerase reverse transcriptase(hTERT)gene.Methods The plasmid pIRES2-EGFP and plasmid pIRES2-EGFP-hTERT encoding hTERT were transfected into in vitro cultured human fetal epidermal stem cells by liposome-mediated transfection.Then,the positive cells were selected with G418.The mRNA and protein expressions of hTERT were detected by reserve transcriptase-polymerase chain reaction(RT-PCR)and Western blot.The telomerase activity and the proliferation and cycle of human epidermal stem cells were detected by telomeric repeat amplification protocol(TRAP)-ELISA and flow cytometry respectively.Results RT-PCR and Western blot techniques detected weak mRNA and protein expressions of hTERT gene in untransfected and vacant vector transfected cells but high level of mRNA and protein expressions of hTERT gene in pIRES2-EGFP-hTERT transfected cells.Compared with untransfected and vacant vector transfected cells,the pIRES2-EGFP-hTERT transfected cells had higher telomerase activity,with lower proportion of cells at G_0/G_1 phase,higher proportion of cells at S and G_2/M phases and enhanced proliferation ability.Conclusion Transfection with hTERT gene can markedly enhance mRNA and protein expressions,telomerase activity and proliferation ability of hTERT gene of human epidermal stem cells euhured in vitro.

[Methods] Eighty cases of VD were randomized into two groups by using random number table: group A ( n = 40) was treated with modified Bushen Huoxie Decoction and group B (n = 40) with duxil and nimodipine. After a 3-month treatment, the therapeutic effect of the two groups was evaluated, and mini-mental state examination (MMSE), activities of daily life (ADL) and blood rheology before and after treatment were observed. [Results] The total therapeutic effective rate was 80.0% in group A and 57.5% in group B, the difference being significant ( P

Objective To investigate the changes of interleukin-21 (IL 21) and interleukin-21 receptor (IL 21R) expression level in Crohn's disease (CD) patients before and after accepted infliximab (IFX) treatment.Methods From June 2009 to July 2011,twenty-two CD patients met the research criteria were recruited at Tenth People's Hospital of Tongji University.Patients were treated with infliximab at weeks 0,2,6,and 16 healthy individuals were set as healthy control group at same time.Peripheral blood of healthy control group was taken at regular physical examination and blood of CD patients was taken before treatment and 10 weeks after treatment,intestinal mucosa biopsy samples were taken under colon endoscopy examination.The changes of Crohn's disease activity index (CDAI),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) in CD patients were observed.The change of IL-21R in peripheral blood CD4+ T lymphocytes was detected by flow cytometry.The change of IL-21 expression at mRNA level in intestinal mucosa was determined by realtime quantitative polymerase chain reaction (PCR).The data were analyzed by t test.Results Before treatment,the level of IL21R in peripheral blood CD4+ T lymphocytes of CD patients (12.25％±3.25％) and the expression of IL-21 at mRNA level in inflamed intestinal mucosa (1.38±0.32) were both significantly higher than those of healthy controls (4.25 ％ ± 1.41％,0.44±0.18),the differences were statistically significant (F=15.88,6.75 ; both P＜0.05).At 10th week,the level of IL-21R in peripheral blood CD4+ T lymphocytes of CD patients (8.12％ ± 2.05％) and the expression of IL-21 at mRNA level in intestinal mucosa (0.77 ± 0.24) were both significantly lower than those before treatment,the differences were statistically significant ( t=4.880,8.019; both P＜0.01).Before treatment,ESR,CRP and CDAI of CD patients was (46.8±11.4) mm/1 h,(52.4±11.5) mg/L and 319±74,which was (23.5±9.0) mm/1 h,(11.6±4.6) mg/L and 113±42 after treatment,the differences were statistically significant (t=9.485,16.458,11.100; all P＜0.05).Conclusion The IL-21 expression of active CD patients decreases after IFX treatment,which indicates that IL-21 may involve in IFX induced clinical remission of active CD.

Objective To observe the effect of Shujinkeli on stroke patients with spastic hemiplegia. Methods The double blind test was applied in this study. 77 stroke patients with spastic hemiplegia were randomly divided into the group A (n=38) and the group B (n=39). Under the guidance of the criterion and routine treatment, patients of the group A were treated with Shujinkeli A and patients of the group B were treated with Shujinkeli B. After treatment, curative effect of patients was evaluated. Results The group A was the treatment group, and the group B was the control group. After treatment, the treatment group was superior to the control group in the improvement of muscular tension, Fugel-Meyer score and Barthel index. Conclusion The Shujinkeli can make the high muscular tension lower, which will accelerate the disabled limbs' recovery and improve patients' motor function and self-care ability of daily life.

Objective To analyze expression of interleukin (IL)-23p19 and IL-23 receptor (IL-23R) in inflammatory bowel disease (IBD),and the role in the induction of peripheral blood T cell activation and proinflammatory cytokine secretion.Methods Peripheral blood (PB) and intestinal mueosal biopsies were collected from 12 patients with Crohn's disease (CD),25 patients with ulcerative colitis (UC) and 20 healthy controls.Expression of IL-23p19 was determined by immunohistochemistry and RT-PCR.IL-23R expression in CD4+,CD8+ T and NK cells from peripheral blood and lamina propria was analyzed by flow eytometry.Peripheral blood mononuclear ceils (PBMC) were isolated and cultured under stimulation with IL-23 and anti-CD3,and the levels of tumor necrosis factor α (TNFα) interferon (IFN)γ and IL-2 were determined by enzyme-linked immunosorbent assay (ELISA).Results The expression of II.-23p19 was significantly increased in inflamed mucosa of CD at both the transcriptional and translational levels compared with that in UC and healthy controls.IL-23R was mainly expressed in PB- and lamina propria-CD4+,CD8+T cells and NK cells from IBD patients,and markedly increased compared with controls (P＜0.05).IL-23 strongly triggered PBMC from IBD patients to produce significantly higher levels of IFN-γ,TNF-α and IL-2(P＜0.05).Conclusions IL-23p19 and IL-23R are highly expressed in IBD,particularly in CD,and may play an important role in the induction of T cell activation and proinflammatory cytokine secretion,suggesting that targeted therapy directed against IL-23 may have a therapeutic role in IBD.

OBJECTIVE: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. METHODS: One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. RESULTS: The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. CONCLUSION: The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

OBJECTIVE: To explore the clinical evaluation system reflecting the superiority and characteristics of comprehensive traditional Chinese medicine (TCM) therapy for acute stroke. METHODS: A randomized controlled trial with single blind in various therapeutic centers was applied on the patients with the acute stage of hemorrhagic stroke due to hypertension, who were allocated to the trial group and the control group. The trial group accepted the general Western medicine therapy and differential treatment of traditional Chinese medicine based on stage classification. Patients in the control group were treated with the general Western medicine and the placebo of traditional Chinese herbal medicine. The treatment effect was assessed at the 7th day, 14th day, 21st day, and 28th day of post-treatment and after 3-month follow-up. The clinical evaluation system included the syndromes of TCM (ZH), Glasgow coma standard (GCS), nerve functional failure (NF), activity of daily living (ADL), Barther index (BI), quality of life index (QLI) and functional activities questionnaire (FAQ). RESULTS: Four hundred and four patients with acute stroke were included. There were 178 cases with yang-syndrome and 21 cases with yin-syndrome in the trial group (n=199), and there were 165 cases with yang-syndrome and 40 cases with yin-syndrome in the control group (n=205). The rates of recovery and obvious improvement after 3-month treatment in the trial group and the control group were 86.5% and 73.6% respectively. There was significant difference between the two groups (P<0.01). The response sensitivity of the effect items indicated that the sensitivity of GCS began to increase from the 7th day and was high at the 14th day and the 21st day for all patients. The response sensitivity of the NF scale was high for all patients at the 14th day, the 21st day and the 28th day. The BI scale and the QLI scale were sensitive to the patients with light and middle stage of stroke at the 21st day, and were sensitive to the patients with light stage of stroke after 3-month follow-up. The FAQ scale was sensitive to the light stroke at the 21st day and after 3-month follow-up. The ADL scale was sensitive to all patients at the 28th day and the patients with light stage of stroke after 3-month follow-up. The ZH scale was sensitive to all patients from 0 to 7d, the 14th day, and the 28th day. The principle components analysis indicated these 7 items could reflect the condition of stroke from 0-7d, the 21st day and after 3-month follow-up, and could be used to evaluate the therapeutic effect of hemorrhagic stroke. ZH scale and FAQ scale were more sensitive than other effect items at the 28th day. CONCLUSION: The seven items (GCSbNFbBIbQLIbFAQbADLbZH) have high sensibility to all patients in the acute stage of hemorrhage stroke especially at the 21st day. The ZH score will change in accord with the condition of stroke, and is appropriate to reflect the condition of stroke. It is believed that the seven items can form the system of effect evaluation in different stages of stroke, and the ZH scale is a very important item.

Objective To understand the level of urinary iodine of schoolchildren and salt iodine content of their families in a primary school and to analysis influence between salt iodine content and urinary iodine level in Haimen City,Jiangsu Province.Methods A cross-sectional study was conducted in a primary school of Haimen City in 2012.With the method of stratified cluster sampling,all students aged 9 ～ 12 were extracted in grades 3-5,urine samples and salt samples of their family were collected.Urinary iodine and salt iodine were determined according to Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry (WS/T 107-2006) and Direct Titration of Universal Test method in Salt Industry (GB/T 13025.7-1999).Results Totally,452 students from grades 3-5,including 233 boys and 219 girls were selected by cluster-stratified sampling.The median of children's urinary iodine was 231.90 μg/L,while the median of boys and girls was 235.40 and 222.60 μg/L,respectively.The median of urinary iodine of 9,10,11 and 12 year old students was 253.65,195.70,236.40 and 241.70 μg/L,respectively.The proportion of less than 100 μg/L and ≥300 μg/L was 7.7％ (35/452) and 27.7％ (125/452),respectively.There were no significant differences between different gender and age students.Among the 452 salt samples collected the median of salt iodine was 27.50 mg/kg.The coverage rate of iodized salt,the qualified rate of iodized salt and the intake rate of qualified iodized salt were 98.9％ (447/452),95.1％ (425/447) and 94.0％ (425/452),respectively.After consumptionn of non-iodized salt (＜ 5 mg/kg),unqualified iodized salt(5 ～ ＜ 20 mg/kg or ＞ 50 mg/kg) or qualified iodized salt [(35 ± 15)mg/kg],the median of urinary iodine of children was 177.30,211.95 and 232.90 μg/L,respectively.Correlation analysis showed that there was no relationship between iodine content of salt and urinary iodine level of schoolchildren (r =0.085,P ＞ 0.05).Conclusions Current nutritional level of schoolchildren in Haimen City is higher than the appropriate amount.Household salt iodine content of edible salt does not affect urinary iodine level of the children significantly.

Radiation-induced brain injury (RBI) is a common long-term complication of radiotherapy for nasopharyngeal carcinoma (NPC) and seriously affects the quality of life and overall survival of patients. In the era of intensity-modulated radiation therapy (IMRT), the long-term complications after radiotherapy, especially RBI, are becoming increasingly concerning because a number of treated patients with NPC obtain long-term survival. At present, the understanding of RBI is still being explored, and its pathogenesis and treatment methods are continuously updated. This article reviews the research progress of RBI in patients with NPC.
