1.Progress of germinal matrix intraventricular hemorrhage in the premature infant
International Journal of Pediatrics 2011;38(2):117-120
Of all types of intracranial hemorrhage (ICH) in the neonates, germinal matrix intraventricular hemorrhage(GM-IVH) in the premature infant is the most common type, mainly attributed to the existence of immature germinal matrix, lt's usually lack of visible and specific symptoms and signs in the nervous system, so its early and final diagnosis depends on the imaging examine. GM-IVH can cause periventricular hemorrhagic infarction, post-hemorrhagic hydrocephalus, periventricular leukomalacia and the associated cerebellar hemorrhagic injury, which are critical determinants of neonatal morbidity, mortality, and neurodevelopmental outcome in the survivors. The overall aim of this article is to review the current knowledge of the cause,mechanisms, imaging diagnosis, complication, management and outcome of GM-IVH in the preterm infant.

Method 118 patients with vocal cord polyp from November 2013 to August 2015 in our hospital were chose as research subjects, all patients were divided into observation group (n=54) and control group (n=64) accord﹣ing to different treatment. Control group: patients received conventional laryngoscope resection; observation group:patients received CO2 laser under suspension laryngoscope. Then compare the two group patients' voice indexes, a﹣cute phase proteins, rehabilitation and recovery speed after treatment. Results Observation group patients' F0, HNR values were higher than control group patients, PPQ, APQ, NNE values were lower than that in control group (P<0.05);early observation group patients' postoperative serum CRP, α1-AG, CER,β2-MG values were lower than con﹣trol group patients, ALB value was higher than control group patients (P< 0.05); observation group patients' cure rate was higher than control group patients, valid and invalid rates were lower than control group patients, the first sound time, sound full recovery time, discharge time were shorter than control group patients (P< 0.05). Conclusion Vocal cord polyp patients receive laser under suspension laryngoscope treatment, can effectively promote recovery rate, have advantages of minimally invasive and rapid recovery after surgery.
4.Research on the progress of EGFR inhibitors in tumor inhibition and radio-sensitization
Chinese Journal of Clinical Oncology 2015;42(11):580-584
Radiotherapy is important in cancer treatment, but improving the therapeutic effect of irradiation and decreasing its toxicity to normal human tissues is still a global problem. Epidermal growth factor receptor (EGFR) is a member of ErbB family and is an important transmembrane receptor with signal-transduction tyrosine kinase activity. EGFR can direct cellular migration, adhesion, proliferation, differentiation, and apoptosis, and plays a fundamental role in the development and growth of many types of human tumor cells. A series of preclinical studies showed that EGFR inhibitors can enhance the antitumor activity of ionizing radiation. EGFR inhibi-tors regulate radio-sensitization through multiple mechanisms, including cell cycle alterations, DNA repair modulation, and anti-angio-genesis. Reasonable application of EGFR inhibitors will effectively increase the radio-therapeutic effect, extend the local control of tu-mor, and improve a patient's quality of life.
5.Importance of Clinical Diagnosis and Treatment in Non-variceal Vascular Originated Gastrointestinal TractHemorrhage
Chinese Journal of Gastroenterology 2017;22(8):452-455
Gastrointestinal bleeding is a severe,complicated and commonly seen disease in Department of Digestive Diseases,the frequent etiology is peptic ulcer,acute gastric mucosal lesion,esophageal gastric varices and digestive tract tumors. In recent years,clinicians gradually noticed a kind of disease characterized by acute,recrudescent and life-threatening bleeding,that is the non-variceal vascular originated gastrointestinal hemorrhage. The guidelines and scholars have not paid enough attention to this problem. However,non-variceal vascular originated gastrointestinal hemorrhage is not uncommon,and is difficult and tricky in its management for clinicians. Therefore,clinicians should pay sufficient attention to the characteristics and therapeutic principles of non-variceal vascular originated gastrointestinal hemorrhage.
6.Research progress on P300/CBP in malignant tumors
Practical Oncology Journal 2014;(2):188-192
P300/CBP is one of the most important high molecular weight protein histone acetyltransferase ( HAT) Although it is encoded by multiple different genes , P300/CBP is highly homologous , Because they have the similar amino acid sequence and functions ,and belong to the same class of proteins ,normolly they are all called P300/CBP.P300/CBP is involved in the activation of many kinds of transcription factors ,the protein itself alsohas acetyltransferase activity ,and is capable of acetylation of 4 core histones and transcription factor .More and more studies have confirmed the relationship of P 300/CBP variation withmultiple human diseases , including in-flammation,diabetes,heart disease and especially cancer .In tumor P300/CBP is associated with some pathways , and these pathways play a different roles in the tumor .Although P300/CBP is usually regarded as a tumor sup-pressor factor ,is plays different roles in different tumors ,This review mainly introduces the relationship of P 300/CBP with some solid tumor disease genes ,related transcription factors and their signaling pathways .
9.Comparison of Therapeutic Efficacy and Safety of Dexamethasone with Different Administration Routes in the Treatment of Chronic Secretory Otitis Media
China Pharmacy 2017;28(21):2919-2922
OBJECTIVE:To compare therapeutic efficacy and safety of dexamethasone with different administration routes in the treatment of chronic secretory otitis media. METHODS:A total of 150 patients with chronic secretory otitis media were random-ly divided into control group(75 cases)and observation group(75 cases). Control group was given Dexamethasone sodium phos-phate injection 5 mg by auripuncture under endoscope. Observation group was given Dexamethasone sodium phosphate injection 5 mg via eustachian tube under endoscope. Both groups were given relevant medicine every 2 days,for 3 times in total. Clinical effi-cacies of 2 groups were observed as well as bone conduction threshold under 1,2,4,8 kHz,the levels of water channel protein 1 and water channel protein 4,recurrence,the occurrence of tympanic cavity effusion before and after treatment. The occurrence of ADR was recorded. RESULTS:The total response rate of observation group(93.33%)was significantly higher than that of control group(80.00%);recurrence rate and the incidence of tympanic cavity effusion of observation group were significantly lower than those of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in bone con-duction threshold,the levels of water channel protein 1 and water channel protein 4 between 2 groups(P>0.05). After treatment, the levels of bone conduction threshold in 2 groups were significantly lower than before;the observation group was significantly lower than the control group. The levels of water channel protein 1 and water channel protein 4 in 2 groups were significantly high-er than before;the observation group was significantly higher than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:The administration of dexa-methasone via eustachian tube under endoscope is significantly better than auripuncture in terms of therapeutic efficacy for chronic secretory otitis media,relieving clinical symptom,improving bone conduction threshold,up-regulating water channel protein level, reducing the risk of recurrence and tympanic cavity effusion. The two routes of adimistration have similar safety.
10.Role of Helicobacter pylori Eradication in Diarrhea-predominant Irritable Bowel Syndrome
Chinese Journal of Gastroenterology 2017;22(8):482-485
Background:Irritable bowel syndrome (IBS)is a commonly seen functional intestinal disorder. The association between Helicobacter pylori (Hp)infection and IBS is not clarified yet. Aims:To investigate the role of Hp eradication in diarrhea-predominant IBS (IBS-D)and the relationship between Hp infection and IBS-D. Methods:A total of 335 IBS-D patients and 335 health examination subjects were recruited from Jan. 2009 to Dec. 2015 at Transportation Center Hospital of Yunnan Province and People's Hospital of Xishuangbanna Dai Autonomous Prefecture. All IBS-D patients were hospitalized patients and fulfilled the Rome Ⅲ criteria. Positive for both rapid urease test and 14 C-urea breath test was defined as Hp infection. Hp-positive IBS-D patients recruited in 2005 received Hp eradication therapy and were allocated into two groups according to the results of eradication therapy. Pinaverium bromide and montmorillonite powder were given in both groups and the clinical efficacy for IBS symptoms was assessed after treatment and followed up for 6 months. Results:The Hp infection rate of IBS-D patients was significantly higher than that in healthy controls (53. 7% vs. 41. 8%,P < 0. 05). In IBS-D patients received Hp eradication therapy,51 were allocated into eradicated group and 26 into non-eradicated group. No significant differences were observed in individual symptoms including abdominal pain/discomfort,bloating and stool frequency and the overall efficacy for global symptoms (68. 6% vs. 65. 4%)between the two groups (P > 0. 05). After a 6-month follow up,the differences were still insignificant (P > 0. 05). Conclusions:Hp infection is more prevalent in IBS-D patients than in general population,however,eradication of Hp has no impact on IBS symptoms. The association between Hp infection and IBS-D needs further study.
