Objective Aim to explore the effect of hyperglycemia on the expression of glucose transporter 1 (GLUT-1)in rats at the acute phase of traumatic brain injury.Methods Adult male SD rats were randomly divided into 3 groups: normal control group, traumatic brain injury group and insulin treated group.The blood glucose concentration of the rats was measured before and after injury.The expression of GLUT-1 gene and protein in the injured and uninjured cortex was detected by reverse transcription polymerase chain reaction (RT-PCR) and western-blot.The apoptosis in the injured and uninjured cortex were detected by TUNEL staining.Results The blood glucose concentration increased markedly in traumatic brain injury group.The expression of GLUT-1 gene and protein in the injured cortex decreased in both the traumatic brain injury group and the insulin treated group.In contrast, the expression of GLUT-1 gene and protein significantly increased at 12 h, 24 h, 48 h, 72 h after injury in the insulin treated group compared with control(P＜0.01).The number of apoptotic cells in the insulin treated group were significantly larger than that in the traumatic brain injury group at each time point(P＜0.01).However, The number of apoptotic cell death remained unchange in the uninjured cortex in each group(P＞0.05).Conclusions The hyperglycemia after traumatic brain injury may increase the apoptotic cells in the injured brain through decreasing the expression of GLUT-1.

Objective:To study the influence of thrombus aspiration combined tirofiban on patients with acute ST seg-ment elevation myocardial infarction (STEMI)after primary percutaneous coronary intervention (PCI).Methods:A total of 98 patients,who received primary PCI because of STEMI in our hospital from Jan 2012 to Mar 2013,were selected.They were divided into thrombus aspiration group (n=48,received pure thrombus aspiration)and com-bined treatment group (n = 50,received thrombus aspiration combined intracoronary tirofiban injection during PCI).Coronary angiography (CAG)instantly after PCI and follow-up condition during hospitalization and six months after discharge were compared between two groups.Results:(1)Compared with thrombus aspiration group after PCI,there were significant rise in TIMI blood flow grade [(2.3±0.6)grades vs.(2.7±0.3)grades],per-centage of TIMI flow grade 3 (72.9% vs.90.0%)and ST segment regression >50% rate within 90min after PCI (52.1% vs.74.0%),P < 0.05 or < 0.01,and significant reduction in percentage of postoperative no-reflow (18.8% vs.4.0%,P =0.038)in combined treatment group in hospital;(2)After six-month follow-up,left ven-tricular ejection fraction (LVEF)of combined treatment group was significantly higher than that of thrombus aspi-ration group [(58±6.3)% vs.(51±5.6)%,P <0.05].Conclusion:Thrombus aspiration combined tirofiban can effectively reduce coronary thrombus burden and improve cardiac function in STEMI patients during primary PCI.

Objective To explore the effects of Yiqi Jianpi decoction on inflammatory reaction, immune function and nutritional status in patients after surgery of laparoscopic rectal cancer. Methods Eighty-two patients with post-operative laparoscopic rectal cancer resection admitted to Pingxiang People's Hospital from June 2017 to March 2019 were enrolled, and according to whether traditional Chinese medicine (TCM) was used or not, they were divided into a western medicine treatment control group (control group) and a combined traditional Chinese and western medicine treatment group (combined group), 41 cases in each group. The control group was treated with symptomatic conventional western therapy, while the combined group was additionally treated with Yiqi Jianpi decoction based on the conventional western treatment as in the control group; the composition of the decoction: hedyotis herba, herba agrimoniae, radix astragali each 30 g; radix codonopsis, ganoderma lucidum each 20 g; rizoma atractylodes, poria cocos and prunella chinensis 15 g each; pinellia ternata 9 g, licorice root 6 g; all the above ingredients were together boiled with water and the fluid (decoction) was filtered, 150 mL once orally taken, twice a day, 21 days constituting one therapeutic course, and the clinical efficacy was evaluated after 1 course of therapy. The changes of TCM syndrome score, simple health situation scale (SF-36) score, inflammatory indexes, immune function and nutritional status of the two groups were observed before and after treatment. Results After treatment, the levels of TCM syndrome score, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and CD8+ in the two groups were significantly lower than those before treatment, while the levels of SF-36 score, CD4+, CD4+/CD8+, transferrin (TRF) and albumin (Alb) were significantly higher than those before treatment (all P < 0.05), and the degree of changes in the combined group were more significant than those in control group [TCM syndrome score: 3.79±2.22 vs. 6.86±2.02, SF-36 score:75.18±4.13 vs. 64.17±4.01, CRP (mg/L): 4.54±1.31 vs. 5.71±2.21, IL-6 (μg/L): 20.21±2.21 vs. 26.12±2.13, TNF-α (μg/L): 33.04±4.56 vs. 36.41±3.23, CD4+: 0.37±0.03 vs. 0.35±0.03, CD8+: 0.25±0.03 vs. 0.28±0.03, CD4+/CD8+: 1.51±0.39 vs. 1.19±0.37, TRF (g/L): 3.05±0.41 vs. 2.28±0.42, Alb (g/L): 43.88±2.28 vs. 39.86±2.03, all P < 0.05]. Conclusion Yiqi Jianpi decoction in the treatment of patients after surgery of laparoscopic rectal cancer can effectively promote the recovery of gastrointestinal function, reduce the inflammatory reaction, elevate the immune function and improve clinical prognosis.

Objective To generate minichromosome maintenance protein 2(MCM2)gene knockout cervi-cal cancer HeLa cell lines using inducible CRISPR/Cas9 technology,and to explore the effect of MCM2 on DNA replication and replication stress.Methods The inducible CRISPR/Cas9 system,TLCV2,was used to construct MCM2 knockout HeLa cell lines.And the cell lines were divided into control group(Control),knockout group 1(KO1),and knockout group 2(KO2).Western blot,Edu incorporation experiment,real-time quantitative PCR(qPCR),immunofluorescence and MTT assay were used to analyze the effects of MCM2 knockout on DNA replica-tion and replication stress induced by hydroxyurea.Results The CRISPR/Cas9 system successfully knocked out the MCM2 gene after induction,and MCM2 knockout affected the stability of MCM2-7 complex.Compared with the control cells,MCM2 knockout cells had a dramatic decrease in the capacity of DNA replication,and the mRNA levels of Cyclin A1,Cyclin E1 and CDK4.Under DNA replication stress,MCM2 knockout cells decreased cell viability,DNA damage repair capacity,and increased genomic instability compared with control cells.Conclusion Knockout of MCM2 gene reduces the DNA replication capacity of HeLa cells under normal conditions and cell viability under replication stress.This study successfully generates MCM2 gene inducible knockout HeLa cell lines,laying the foundation for further research on the role and biological function of MCM2 gene in the occurrence and progression of cervical cancer.

OBJECTIVETo investigate the role of NF-κB/survivin signal pathway in the intima hyperplasia of rat carotid balloon injury restenosis model.

METHODSNF-κB siRNA lentivirus vector (titer was 1 × 10⁸ TU/ml) was established. Carotid balloon injury restenosis model was made in 33 SD rats. The rats were divided into 4 groups according to different processing methods, including negative control (NC) group (n = 11), NF-κB siRNA group (n =11), NF-κB siRNA+YM155 (survivin inhibitor) (n = 11), the uninjured carotid artery served as the normal control group (n = 11). After 7 days, the carotid sample (n = 5 each group) were harvested to detect the NF-κB and survivin mRNA expression by RT-PCR.The carotid sample were harvested on 28 days (n = 6 each group) for HE staining and measuring intima hyperplasia. Immunohistochemical method was also used to detect the expression of intima proliferation cell nuclear antigen (PCNA) and media α-SM-actin.

RESULTS(1) After 7 days, NF-κB and survivin mRNA expression was significant higher in NC group than in normal control group (P<0.05), the NF-κB mRNA expression was significantly lower in NF-κB siRNA group than in NC group (P<0.05) and similar between NF-κB siRNA group and NF-κB siRNA+YM155 group. The survivin mRNA expression was significantly lower in NF-κB siRNA group compared to NC group (P<0.05) and significantly higher in NF-κB siRNA group than in NF-κB siRNA+YM155 group (P<0.05). (2) After 28 days, intima hyperplasia was observed in NC (0.13 ± 0.01), NF-κB siRNA (0.11 ± 0.01) and NF-κB siRNA+YM155 group (0.09 ± 0.01) mm² (P<0.05). Media area was similar among NC group, NF-κB siRNA group and NF-κB siRNA+YM155 group (P>0.05). I/M ratio was gradually reduced among NC group (1.55 ± 0.07), NF-κB siRNA group (0.92 ± 0.08), NF-κB siRNA+YM155 group (0.76 ± 0.06, all P<0.05). Similar results were found in the residual restenosis rate: NC group (58.71 ± 0.02) %, NF-κB siRNA group (32.13 ± 0.05) %, NF-κB siRNA+YM155 group (26.42 ± 0.03) % (all P<0.05) and expression of vascular smooth muscle cell PCNA: NC group (45.32 ± 7.21) %, NF-κB siRNA group (36.54 ± 6.42) %, NF-κB siRNA+YM155 group (28.57 ± 6.31) % (all P<0.05). On the contrary, the IOD of α-SM-actin in media increased gradually: NC group (0.055 ± 0.006), NF-κB siRNA group (0.072 ± 0.011), NF-κB siRNA+YM155 group (0.084 ± 0.008, all P<0.05).

CONCLUSIONInhibiting NF-κB expression can significant decrease intima hyperplasia in this model, and this effect may be mediated by inhibiting survivin and reducing the proliferation of vascular smooth muscle cells.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
