0bjective To study the expression of Fas in hippocampus of cerebral ischemia-reperfusion rats after treatment with monosialoganglioside (GM1). Methods Seventy-two SD rats were randomly divided into sham group (n=8), GM1 treatment group (n=32) and ischemia-reperfusion (I/R) group (n=32). According to the different time points (6 h, 12 h, 24 h and 3 d) of I/R, there were four subgroups in GM1 and I/R groups respectively. The expression of Fas in hippocampus was examined by immunochemistry and Western blot methods in all groups. Results Results of immunochemistry method showed that there was a little expression of Fas (the mean optical density was 0.17±0.02) in hippocampus of sham group, and the positive expression of Fas at different time points were increased significantly after reperfusion. The mean values of opti-cal density at different time points were 0.42±0.11, 0.51±0.13, 0.55±0.13 and 0.62±0.15 in I/R group, which reached to the peak at 3 d . The positive expression of Fas at different time points were significantly decreased in GM1 group (0.29 ± 0.09, 0.34±0.11, 0.37±0.12 and 0.43±0.12) than that of I/R group (P＜0.05). Conclusion Monosialoganglioside participated in the pathogenesis of cerebral ischemia-reperfusion injury by down-regulating the expression of Fas.

OBJECTIVETo observe the clinical effects of acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" (activating blood and eliminating wind, soothing liver and strengthening spleen) on morning blood pressure in patients with cerebral infraction combined with essential hypertension.

METHODSSixty-eight patients were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the two groups were treated with acupuncture method of "Xingnao Kaiqiao" (consciousness-restoring resuscitation) and oral administration of nifedipine. In addition, patients in the observation group were treated with acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" that met the criteria of standard manipulation, in which bilateral Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3) were selected. The treatment was given once a day, five times a week, for totally six weeks. The improvement and control rate of morning blood pressure in the two groups were observed.

RESULTS(1) After treatment, the morning blood pressures were decreased significantly in the two groups (all P < 0.05); after 15 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was superior to that in the control group, but the difference was not significant (both P > 0.05); after 30 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was significantly superior to that in the control group (both P < 0.05). (2) After 30 treatments, the control rate of morning blood pressure in the observation group was significantly higher than that in the control group [82.4% (28/34) vs 58.8% (20/34), P < 0.05].

CONCLUSIONAcupuncture method of "Huoxue Sanfeng, Shugan Jianpi", characterized with standard manipulation criteria, can effectively control morning blood pressure in patients with cerebral infraction combined with essential hypertension.

AIM: To detect whether N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) inhibits epithelial-mes-enchymal transition in A549 cells induced by TGF-β1 through suppressing the expression of heat shock protein 27 (HSP27) and zinc finger proteins Snail (including SNAI1and SNAI2) which ultimately inhibited the deposition of type I and type III collagens.METHODS:The colocalizations of HSP27 and SNAI1/SNAI2 respectively on A549 alveolar epi-thelial cells induced by TGF-β1 were measured by confocal microscopy .The expression of HSP27, SNAI1 and SNAI2 at mRNA level was detected by real-time PCR.Western blotting analysis was used to detect the expression of HSP 27, SNAI1 and SNAI2 on epithelial-mesenchymal transition in A549 cells induced by TGF-β1 and also the deposition of type I and type III collagens in A549 cells transfected with HSP27shRNA prior to TGF-β1 stimulation.RESULTS: Compared with control group, TGF-β1 increased the expression of HSP27, SNAI1, SNAI2, type I and type III collagen, which decreased significantly followed by Ac-SDKP intervention.The expression of SNAI1, type I and type III collagen decreased signifi-cantly after transfected with HSP27shRNA in A549 cells, which had the similar effect on Ac-SDKP intervention.CON-CLUSION:Ac-SDKP inhibits the transition of cultured A 549 cells to myofibroblasts and attenuates collagen synthesis by suppressing the expression of HSP 27 and zinc finger proteins SNAI 1 and SNAI2.

Objective To observe the effect of methylene blue on the expression of liver inducible nitric oxide synthase (iNOS) in rats with different stages of sepsis.Methods One hundred and twenty-six adult female Wistar rats were randomly divided into three groups: sham operation group, sepsis group and methylene blue group, each group was again subdivided into 0, 6, 12, 18, 24, 30, 36 hours subgroups, each subgroup6 rats. The model of sepsis was established by cecal ligation and puncture (CLP) method, and in the sham operation group, the abdominal incision was performed and the intestinal mesentery was separated only, without ligation and perforation. In methylene blue group, 15 mg/kg methylene blue was injected into a caudal vein at 0, 6, 12, 18, 24, 30, 36 hours after CLP in the rats in corresponding subgroups, respectively; in the sepsis and sham operation subgroups, the same amount of 0.9% normal saline was given. After administration for 6 hours in various groups, the rats were sacrificed and the liver tissue was harvested immediately. The expression of iNOS mRNA of liver tissues was determined by the real-time fluorescent quantitative reverse transcription-polymerase chain reaction (qRT-PCR),and the protein expression of iNOS was determined by Western Blot.Results Compared with sham operation group, the liver tissue expression of iNOS mRNA was significantly up-regulated in sub-sepsis groups at 0, 6, 12 and 18 hours after CLP (2-ΔΔCt: 16.66±2.81 vs. 1.00±0.36, 12.26±5.78 vs. 1.00±0.30, 6.08±1.33 vs. 1.00±0.18, 2.42±0.64 vs. 1.00±0.12, allP < 0.01), after 24 hours the expression of iNOS mRNA had no significant change; the liver tissue expression of iNOS protein was obviously up-regulated in sub-sepsis groups at 6, 12 ,18 and 36 hours after CLP (gray value: 0.350±0.011 vs. 0.210±0.005, 1.460±0.085 vs. 0.090±0.005, 0.230±0.012 vs. 0.18±0.008, 0.310±0.017 vs. 0.200±0.010, allP < 0.01). Compared with sepsis group, the expression of the liver tissue iNOS mRNA was down-regulated in methylene blue subgroups at 0, 12 and 18 hours after CLP (2-ΔΔCt: 9.90±3.06 vs. 16.66±2.81, 1.56±0.58 vs. 6.08±1.33, 1.11±0.15 vs. 2.42±0.64, allP < 0.05), and the expression of iNOS protein was down regulated in methylene blue subgroups at 6, 12, 18 and 36 hours after CLP (gray value: 0.150±0.008 vs. 0.350±0.011, 0.950±0.009 vs. 1.460±0.085, 0.150±0.007 vs. 0.230±0.012, 0.170±0.009 vs. 0.310±0.017, allP < 0.05).Conclusion Zero-24 hours after CLP, the expressions of mRNA iNOS and protein in liver of septic rats are significantly increased; methylene blue can markedly inhibit the expressions of iNOS mRNA and protein in the liver of rats with sepsis.

[Abstract ] Objective Silicosis is one of the most serious occupational diseases in China .In this study,we explored the reg -ulatory effect of N-acetyl-seryl-aspartyl-lysyl-proline ( Ac-SDKP ) on angiotensin ( Ang ) Ⅱ-induced extracellular signal-regulated ki-nase ( ERK1/2) and Jun N-terminal kinase ( JNK) signals and its inhibitory effect on the differentiation of human embryonic lung MRC-5 fibroblasts to myofibroblasts via Ang Ⅱ-induced ERK1/2 and JNK signals . Methods Human embryonic lung MRC-5 fibro-blasts were induced by Ang Ⅱand pre-treated with the JNK signal inhibitor ( SP600125 ) , the ERK1/2 signal inhibitor ( PD98059 ) or Ac-SDKP.The proliferation of the cells was measured by MTT assay .The expressions of αS-MA, SRF, p-ERK1/2 and p-JNK were determined by immunocytochemical staining , and the expression levels of these proteins and collagen Ⅰwere detected by Western blot .Results The A value of Ang Ⅱ group (0.56 ±0.08) measured by MMT assay was 2.07 fold as control group ( 0.27 ±0.05 ). Pretreatment with SP600125 , PD98059 and Ac-SDKP, the A value were (0.39 ±0.02), (0.40 ±0.03) and (0.36 ±0 0.5) that had a statistical significance with Ang Ⅱgroup.The up-regulation of colla-gen type Ⅰ,α-SMA, SRF were induced by Ang Ⅱ by 4.50, 3.50 and 3.00 fold compared with control group.Moreover, the expression of p-ERK1/2 and p-JNK were increased as 6.71 and 7.90 fold as control. Pre-treatment with Ac-SDKP could inhibit p-JNK and p-ERK1/2 to 29.79% and 46.84% compared with AngⅡ group. Conclusion Ac -SDKP can inhibit the differentiation of human embryonic lung MRC-5 fibroblasts to myofibroblasts by regulating AngⅡ-induced JNK and ERK1/2 signals.

Objective:To explore the differences and similarities of the neuropsychological functioning defi-cits in children between Tourette syndrome (TS)and attention-deficit/hyperactivity disorder (ADHD). Methods:Thirty boys with TS-only,36 with TS-plus-ADHD,36 with ADHD were selected from out-patient department,and 50 normal boys (NC)matched with gender,age and IQ were recruited as the controls. Patients'diagnosis was made according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10). They were assessed with the Stroop Color-Word Interference Test (Stroop)and Purdue Pegboard Test (Purdue)to evaluate the response inhibition and fine-motor coordination respectively. Results:The Stroop scores were higher in children with ADHD than in other groups (P<0. 05 ),there was no difference between children with TS-only and TS-plus-ADHD (P>0. 05 ). All Purdue scores were higher in children with disease than in normal children (P<0. 05 ). Conclusion:The results indicate that the response inhibition deficit may be found in children with ADHD,but not in those with TS-only and TS-plus-ADHD. The neural compensatory mechanism may be re-sponsible for the response inhibition function in children with TS whilst the fine-motor coordination deficit was as-sociated with the disease groups.

Objective To summarize the outcome of nasopharyngeal carcinoma ( NPC) treated by helical tomotherapy in the Chinese PLA general hospital. Methods Between September 2007 and August 2010, 121 newly diagnosed NPC patients were treated by radiotherapy with Tomotherapy system, with ( n =90) or without ( n = 31) concurrent chemotherapy or molecular target therapy. The prescription dose was 70 - 74 Gy/33f to primary tumor and positive lymph node planning target volume,60. 0 - 62. 7 Gy/33f to high risk planning target volume, and 52 -56 Gy/33f to low risk planning target volume. Acute side-effects were evaluated with RTOG/EORTC criteria. Results The remission rate of primary lesion and positive lymph nodes was 95. 0％ and 99. 0％ , respectively. The follow-up rate was 100％ . The number of patients with 1 ,2 and 3 years followed-up were 99 , 49 , and 7. The 1-, 2-and 3-year local relapse-free survival rates were 97. 30％ , 97. 3％ and 97. 3％ , respectively. The 1-,2-and 3-year nodal relapse-free survival rates were 100％ , 100％ and lOO％, respectively. The 1-, 2-and 3-year distant metastasis-free survival rates were 98. 4％ , 96. 3％ and 96. 3％ , respectively. The 1-, 2-and 3-year overall survival rates were 96. 5％ ,92. 6％ and 86. 8％ , respectively. Acute toxicities of skin, oral mucosa and xerostomia with grade 0,1,2 and 3 were 5. 0％ , 74. 4％ , 15. 7％ and 4. 9％ ; 0. 8％ , 37. 2％ , 57. 9％ and 4. 1％ ; 3. 3％ , 53. 7％ ,43. 0％ and 0％ , respectively. Xerostomia restored with time, no grade 2 or more xerostomia was observed 1 year after radiation therapy. Concurrent chemotherapy significantly increased incidence of mucositis,esophagitis and tracheitis. Conclusion Helical tomotherapy is efficient, secure and effective modality for the treatment of nasopharyngeal carcinoma.

Ovarian cancer is a heterogeneous malignant tumor,one of the most common causes of cancer death in women worldwide,and there is currently no effective treatment available for its treatment,which seriously affects women's life and health.In order to deeply explore the pathogenesis of ovarian cancer and study the specific therapeutic drugs and methods,this paper summarizes,summarizes,assigns and evaluates the clinical characteristics of traditional Chinese and Western medicine for ovarian cancer,and screens out a more complete animal model.Through CNKI,Wanfang,Pubmed and other databases,the relevant content of ovarian cancer animal models was collected and sorted,and the model diagnostic indicators were assigned and the consistency was evaluated.In the evaluation of the model,it is found that the animal model of spontaneous ovarian cancer can simulate the pathogenesis process of human natural ovarian cancer,and the model has high modulus rate,high similarity,and high consistency with the clinical characteristics of traditional Chinese and Western medicine.The subcutaneous tumor graft type model and the blood stasis type model were in good clinical agreement with traditional Chinese medicine,a high degree of similarity,and a longer survival time.At present,animal models of ovarian cancer are mainly based on Western medicine models,and research on animal models consistent with traditional Chinese medicine syndromes is rare.Therefore,the improvement direction of ovarian cancer animal models and the necessity of improving the evaluation system are proposed,so as to make the animal models of ovarian cancer more clinical,and provide a theoretical basis for the determination of the efficacy of traditional Chinese medicine and the discussion of pharmacological effects of ovarian cancer,and provide a theoretical basis for the subsequent research on the pathogenesis and treatment measures of ovarian cancer,in order to improve the model of combining ovarian cancer symptoms in line with the clinical characteristics of traditional Chinese medicine and Western medicine.

To systematically evaluate the effect of vitamin C on prognosis of critically ill patients. Methods Randomized controlled trials (RCT) about vitamin C treatment for critically ill patients were searched in CNKI, CBM, VIP database, Wanfang database, PubMed, Springer Link, Embase, Web of Science, and Cochrane Library from their inception to May 2019. Patients in the treatment group received ascorbic acid while patients in the control group received placebo or other treatment. Outcome measures included mortality, the length of intensive care unit (ICU) stay, the length of hospital stay, and incidence of atrial fibrillation. Two researchers were responsible for literature screening, data extraction and quality evaluation independently. Meta-analysis was performed with RevMan 5.2 software. The publication bias was analyzed by funnel plot. Results A total of 28 RCTs were enrolled and 4 420 patients were included (2 207 in intervention group and 2 213 in control group). Meta-analysis showed that there was no significant difference in mortality between intervention group and control group [odds ratio (OR) = 0.90, 95% confidence interval (95%CI) = 0.75 to 1.08, P = 0.27]. The length of ICU stay [mean difference (MD) = -0.23, 95%CI = -0.29 to -0.16, P < 0.000 01] and the length of hospital stay (MD = -0.96, 95%CI = -1.21 to -0.70, P < 0.000 01) in intervention group were less than those in control group. Subgroup analysis showed that mortality of patients with sepsis and septic shock in intervention group was lower than that in control group (OR = 0.65, 95%CI = 0.43 to 0.99, P = 0.04). For patients undergoing cardiac surgery, the incidence of postoperative atrial fibrillation in intervention group was lower than that in control group (OR = 0.43, 95%CI = 0.34 to 0.54, P < 0.000 01). It was shown by funnel plot that there was less publication bias among studies. Conclusions Vitamin C does not reduce mortality in critically ill patients, but it can reduce the length of ICU stay and hospital stay. In addition, vitamin C can reduce mortality of patients with sepsis and septic shock and reduce the incidence of atrial fibrillation post operation in patients undergoing cardiac surgery.
