Objective To study the effects of Buyang Huangwu decoction(BHD) on serum matrix metalloproteinase-9(MMP-9),high sensitivity C-reactive protein(hs-CRP)levels and inflammatory reaction of patients with ischemic stroke accompanied by Qi deficiency and blood stasis syndrome. Methods Thirty-nine patients with acute ischemic stroke onset for 24-48 hours accompanied by Qi deficiency and blood stasis syndrome were admitted into Nankai Hospital of Tianjin City,and in accordance with the random number table,they were divided into BHD treatment group(21 cases)and conventional western treatment control group(18 cases). The patients in both groups were given conventional western medicine,such as anti-platelet,descent of blood lipid and protection of brain. In the BDH group,the patients were additionally given BHD oral administration. Before and after treatment for 72 hours and 7 days,the changes of serum levels of MMP-9 and hs-CRP were observed in both groups. In the mean time,20 subjects having taken physical healthy examinations in outpatient clinics were assigned in the healthy control group. Results Compared to the healthy control group,before treatment the levels of MMP-9 and hs-CRP in western treatment control and BHD groups were significantly higher than those in the healthy control group〔MMP-9 (μg/L):403.3±32.9,417.9±45.3 vs. 86.5±6.1;hs-CRP(mg/L):7.4±0.7,6.9±0.6 vs. 2.2±0.4,all P<0.05〕. After treatment for 72 hours,the levels of MMP-9 and hs-CRP achieved their peaks,after treatment for 7 days, the levels of MMP-9 and hs-CRP were significantly lower than those at 72 hours in both groups〔the control group:MMP-9(μg/L):190.4±58.0 vs. 528.9±65.1,hs-CRP(mg/L):5.8±0.7 vs. 11.1±0.8;the BDH group:MMP-9 (μg/L):89.5±11.4 vs. 437.6±55.2,hs-CRP(mg/L):3.1±0.9 vs. 7.3±0.6,all P<0.05〕. Conclusions In patients with acute cerebral infarction,the serum levels of MMP-9 and hs-CRP are significantly increased. After conventional treatment,the levels gradually decline,and the descent in the group with addition of BHD is more remarkable,suggesting that BHD have prominent effect for treatment of patients with acute cerebral infarction accompanied by Qi deficiency and blood stasis syndrome.

Liver biopsy had been conducted in some of the patients to compare the tissue changes before and after curing. RESULTS: After being treated with Xuezhikang Capsule, levels of insulin resistance serum lipids and ALT/AST in the patients with non-alcoliolic fatty liver disease had gone downward markedly. The histological observation in some of the patients had improved. No toxicity had been found. CONCLUSION: It is safe and potent to take the small dosage of Xuezhikang Capsule to cure the patients with non-alcoholic fatty liver disease accompanied by hyperlipidemia.

The delivery of bioactive macromolecular substances into cells provides an efficient approach to changing cellular conditions, and is thus of enormously potential therapeutic significance. It has also been an extremely difficult approach due the the impediment and protective nature of cell membrance until the protein transduction domain's (PTD's) capability to ferry macromolecule across cell membrance was discovered. PTD's efficient transductive function has rendered an exciting promise to the clinical treatment of diseases, therapeutic proteins drug development, and basic medical and applied research. The technology has been successfully applied to deliver a variety of substances into cells or tissue organs, and its superior application values have been explicitly demonstrated.

Objective To detect the expression of tumor necrosis factor-α-induced protein-8 like-3 (TIPE3) in colonic mucosa of patients with colon cancer,and to analyze the correlation between its abnormal expression and clinicopathological features of patients with colon cancer.Methods The expression of TIPE3 mRNA in 58 cases of colon cancer and tumor adjacent tissues was detected by realtime polymerase chain reaction (RT-PCR).The expression of TIPE3 at protein level in 83 cases of colon cancer and tumor-adjacent tissues was determined by SP immunohistochemistry.Nonparametric rank-sum test and chi-square test were performed for statistical analysis.Results The relative expression of TIPE3 mRNA in the colon cancer tissues was 0.719 (0.104 to 0.887),which was lower than that of tumor-adjacent tissues (4.770,1.732 to 6.800),and the difference was statistically significant (Z=-6.345,P＜0.05).There was no statistically significant difference in the expression of TIPE3 mRNA in colon cancer tissues between different gender,age and TNM stage (all P＞0.05).The expression of TIPE3 mRNA in group of patients with lymph node metastasis (0.113,0.061 to 0.375) was lower than group of patients without lymph node metastasis (0.489,0.327 to 0.956;Z=3.815,P＜0.01).The expression of TIPE3 mRNA of patients survived less than five years after operation (0.104,0.049 to 0.220) was lower than that of patients survived over five years (0.482,0.266 to 0.908;Z=-3.653,P＜0.01).The expression of TIPE3 mRNA of patients with recurrence after operation (0.188,0.091 to 0.493) was lower than that of patients without recurrence (0.409,0.233 to 1.010;Z=-2.431,P=0.015).The recurrence rate of TIPE3 mRNA high expression group in five years after operation was lower than that of TIPE3 mRNA low expression group (23.1％,6/26 vs 56.2％,18/32);and the difference was statistically significant (x2 =6.508,P＜0.05).The expression of TIPE3 at protein level of colon cancer tissues (44.6 ％,37/83) was lower than that of tumor-adjacent tissues (68.7 ％,57/83;x2 =8.004,P＜0.05).The expression of TIPE3 at protein level was not correlated with age and gender (both P＞0.05).The positive expression rate of patients at stage Ⅱ was higher than that of patients at stage Ⅲ (60.5％,23/38 vs 29.7％,1/37);and the difference was statistically significant (x2 =7.174,P＜ 0.05).The positive expression rate of TIPE3 in group of patients with lymph node metastasis was lower than that of groups of patients without lymph node metastasis (28.2％,11/39 vs 59.1％,26/44),and the difference was statistically significant (x2=7.983,P =0.005).Conclusions The expression of TIPE3 in colon cancer tissues is lower than that in tumor-adjacent tissues.Furthermore,it is correlated with lymph node metastasis,recurrence rate and survival rate.TIPE3 may be involved in the genesis,development,invasion and metastasis of colon cancer.

ObjectiveTo investigate the clinical significance of highly sensitive nucleic acid detection in precise antiviral therapy for patients with liver cirrhosis and its association with aminotransferase level. MethodsA total of 377 patients with hepatitis B cirrhosis who were hospitalized or attended the outpatient service from May 2013 to April 2019 were enrolled and tested by both domestic HBV DNA detection and highly sensitive Cobas HBV DNA detection. All patients underwent biochemical examination, four blood coagulation tests, routine blood test, and upper abdominal computed tomography or ultrasound. Sensitivity of different HBV DNA detection reagents was compared in liver cirrhosis patients with a low viral load, and the correlation between alanine aminotransferase (ALT) level and viral load was analyzed. The paired t-test was used for comparison of continuous data before and after treatment. The receiver operating characteristic (ROC) curve was used to screen out the optimal predictive values of ALT at different cut-off values of HBV DNA. ResultsAmong the 377 patients with hepatitis B cirrhosis, 215 tested positive and 162 tested negative by domestic HBV DNA, and among these 162 patients, 104 (64.2%) tested positive by Cobas HBV DNA detection, with a mean level of 267.5±42.3 IU/ml. After 24 weeks of antiviral therapy, the 104 patients with hepatitis B cirrhosis had significant improvements in viral replication level, ALT, and Child-Pugh score for liver function; HBV DNA decreased from 267.5±32.2 IU/ml before treatment to 59.6±7.7 IU/ml after treatment (t=3.486, P=0.002), ALT decreased from 871±10.8 U/L before treatment to 36.5±7.6 U/L after treatment (t=3.235, P=0.020), and the Child-Pugh score decreased from 6.5±0.7 before treatment to 5.7±0.5 after treatment (t=2.928, P=0.041). The ROC curve analysis of ALT in predicting HBV DNA decision point showed that an ALT level of 29 IU/L was the most sensitive cut-off value for predicting HBV DNA ＜20 IU/ml, with an area under the ROC curve of 0.904, a sensitivity of 1.0, and a specificity of 0.237. ConclusionPrecise detection helps to guarantee the precise clinical treatment of patients with hepatitis B cirrhosis and improve their treatment outcome and prognosis. An ALT level of 29 IU/L is a sensitive indicator for predicting patients with negative Cobas HBV DNA, so as to achieve individualized precise screening and treatment.

Background: Androgenetic alopecia (AGA) leads to thinning of scalp hair and affects 60%~70% of the adult population worldwide. Developing more effective treatments and studying its mechanism are of great significance. Previous clinical studies have revealed that hair growth is stimulated by 650-nm red light. Objective: This study aimed to explore the effect and mechanism of 650-nm red light on the treatment of AGA by using ex vivo hair follicle culture. Methods: Human hair follicles were obtained from hair transplant patients with AGA. Hair follicles were cultured in Williams E medium and treated with or without 650-nm red light.Real-time RT-PCR and immunofluorescence staining were used to detect the expression level of genes and proteins in hair follicles, respectively. RNA-sequencing analysis was carried out to reveal the distinct gene signatures upon 650 nm treatment. Results: Low-level 650 nm red light promoted the proliferation of human hair follicles in the experimental cultured-tissue model. Consistently, 650 nm red light significantly delayed the transition of hair cycle from anagen to catagen in vitro. RNA-seq analysis and gene clustering for the differentially expressed genes suggests that leukocyte transendothelial migration, metabolism, adherens junction and other biological process maybe involved in stimulation of hair follicles by 650-nm red light treatment. Conclusion The effect of 650-nm red light on ex vivo hair follicles and the transcriptome set which implicates the role of red light in promoting hair growth and reversing of miniaturization process of AGA were identified.

Objective To study the effect of age-related white matter changes (ARWMC) on first symptomatic ischemic stroke events in the oldsters. Methods For the prospective study, a total of 368 eligible oldsters were enrolled in the study from January 2010 to August 2012. The degrees of ARWMC were assessed by ARWMC scale;according to the scores, they were divided into non ARWMC group, mild-moderate ARWMC group and severe ARWMC group. The patients were followed up once every 3 months. The clinical endpoint events and time (first symptomatic ischemic stroke, myocardial infarction and all-cause death) were recorded. Analyses of variance and Chi-square test were used to compare the differences of clinical data among the 3 groups. COX regression was used to assess the risk differences of first symptomatic ischemic stroke in the oldsters of three groups. Results After an average of follow-up for 48.7 months, 50 participants (13.6％) had first symptomatic ischemic stroke;25 (25.8％) were categorized as the severe ARWMC group, 22 (10.9％) were as the mild-medium group, and 3 (4.4％) were as the non ARWMC group. Among the three groups, the differences in age, history of hypertension, systolic blood pressure, incidence of clinical endpoint events and first symptomatic ischemic stroke, and follow-up time of endpoint events were statistically significant (P<0.05); patients from the severe ARWMC group were the oldest, and had the longest history of hypertension, the highest systolic blood pressure, the highest incidence of clinical end events and first symptomatic ischemic stroke, and the shortest follow-up period for clinical end events. COX regression analysis showed that the risk of first symptomatic ischemic stroke in the severe ARWMC group was about 8 times higher than that in the non ARWMC group (hazard ratio=9.012, 95％CI: 2.310-35.154, P=0.002). Conclusion In oldsters, severe ARWMC often accompany hypertension history and poor blood pressure controll, and it is an independent and serious risk factor for long-term first symptomatic ischemic stroke.

Background:There is no specific therapy for inflammatory bowel disease(IBD),and the pathogenesis of IBD is not fully clear. Aims:To explore the expression and clinical significance of IL-17BR in colon mucosa and peripheral blood mononuclear cell(PBMC)of patients with IBD. Methods:Colon mucosal biopsy specimens of 40 Crohn's disease(CD) patients,32 ulcerative colitis(UC)patients and 25 healthy controls and PBMC of 30 CD patients,27 UC patients and 25 healthy controls were collected. The expressions of IL-17BR in colon mucosa and PBMC were determined by immunohistochemistry and flow cytometry,respectively,and correlations between IL-17BR expression and levels of CRP, ESR,CDAI score and Mayo score were analyzed. Serum levels of TNF-α before and after infliximab(IFX)treatment were determined by ELISA,and correlations with IL-17BR were analyzed. Results:Compared with healthy controls,IL-17BR expressions in colon mucosa of CD and UC patients were significantly increased(P<0.05). IL-17BR expressions were significantly higher in active CD and UC patients than in remission CD and UC patients(P <0.05). No significant differences in IL-17BR expression in PBMC were found among CD,UC patients and healthy controls(P>0.05). The expression of IL-17BR in colon mucosa was positively correlated with CRP,ESR,CDAI score or Mayo score in CD,UC patients(P <0.05). After treatment with IFX,expression of IL-17BR in colon mucosa and serum TNF-α level were significantly decreased in CD patients(P<0.01). Expression of IL-17BR was positively correlated with serum TNF-α level in CD patients(P<0.05). Conclusions:The increasing of IL-17BR expression in IBD patients is closely correlated with activity of inflammation and TNF-α level. IL-17BR may play a vital role in immune response of intestinal mucosa,and can be used as a new marker for reflecting the activity of IBD.

Human papillomaviruses (HPVs) including high-risk (HR) and low-risk (LR) subtypes have distinguishable variation on both genotypes and phenotypes. The co-infection of multiple HR-HPVs, headed by HPV16, is common in cervical cancer in female. Recently accumulating reports have focused on the interaction between virus and host, particularly the role of human microRNAs (miRNAs) in anti-viral defense by targeting viral genome. Here, we found a well-conserved target site of miRNAs in the genomes of most HR-HPVs, not LR-HPVs, by scanning all potential target sites of human miRNAs on 24 HPVs of unambiguous subtypes of risk. The site is targeted by two less common human miRNAs, miR-875 and miR-3144, and is located in E6 oncogene open reading frame (ORF) and overlap with the first alternative splice exon of viral early transcripts. In validation tests, miR-875 and miR-3144 were identified to suppress the target reporter activity markedly and inhibit the expression of both synthetically exogenous E6 and endogenous E6 oncogene. High level of two miRNAs can inhibit cell growth and promote apoptosis in HPV16-positive cervical cancer cells. This study provides a promising common target of miRNAs for most HR-HPVs and highlights the effects of two low expressed human miRNAs on tumour suppression.
