[ABSTRACT]OBJECTIVETo diagnose laryngopharyngeal reflux (LPR) by using two methods: 24h pH monitoring and RSI combined with RFS scales. To research the voice characteristics of patients with LPR and changes of voice parameters before and after PPIs therapy, and to use voice parameters to help diagnosing and evaluating treatment effect of LPR.METHODSThe patients visited department of Otolaryngology head & neck surgery of Peking University Third Hospital from August 2012 to August 2013 were included in this study. There were 26 LPR patients diagnosed by 24 hr pH-MII monitoring (pH group) and 26 LPR patients diagnosed by RSI combined with RFS (questionnaire group). Another 52 subjects without laryngeal or pharyngeal symptoms were as control group. All subjects underwent MDVP examination. The patients from pH group and questionnaire group took esomeprazole 20 mg bid for one month, afterwards MDVP was examined again. The voice related parameters were compared before and after medication therapy.RESULTSComparing data between LPR patients and normal subjects, Jitter, Shimmer, NHR had significant difference (P<0.05), and F0, MPT had no significant difference (P>0.05) before treatment. After PPIs therapy there was no significant difference between each group (P>0.05).CONCLUSIONAbnormal voice parameters were existed in LPR patients. After PPIs treatment, voice related parameters improved apparently.

Objective To investigate the expression of Ki-67 antigen and Survivin in epithelial ovarian tumor and their relationship.Methods Immunohistochemical assay SP method)was used to examine the expression of Ki-67 antigen and Survivin in 24 cases of benign and 47 cases of malignant epithelial ovarian tumor.Results The staining reaction of Ki-67 was mainly confined to the cellular nucleus.Ki-67 index in malignant tumor(19.59?16.48) was significantly higher than that in benign epithelial ovarian tumor(0.17?0.20)(P

Objective:To study influence of intravenous injection urapidil and nitroglycerin micro pump on blood pressure and heart rate (HR) of hypertension patients undergoing tooth extraction.Methods:116 hypertension patients underwent electrocardiographic monitoring tooth extraction in our hospital from January 2015 to October 2016 were enrolled in this study.According to the random number table method,the patients were divided into observation group and control group with 58 cases,the control group was given nitroglycerin plus pump static point to maintain,the observation group was given intravenous urapidil and pump maintenance,compared the changes of systolic blood pressure (SBP),diastolic blood pressure (DBP) and HR in two groups before operation,at anesthesia,10min after anesthesia,in operation,10 min after operation,and compared the adverse reactions condition of the two groups.Results:The levels of SBP and DBP in two groups in operation and 10 min after operation were significantly lower than that before operation,and the SBP and DBP levels in the observation group in operation were significantly lower than control group,the differences were statistically significant (all P＜0.05).The HR in control group in operation,10 min after operation were significantly higher than before operation,while the observation group were significantly lower control group,the differences were statistically significant (P＜0.05).The total incidence of adverse reactions in the observation group was 6.90％(4/58),which has no significant difference than 10.34％ (6/58) in control group (P＞0.05).Conclusion:Intravenous injection urapidil has little effect on blood pressure and HR in hypertension patients undergoing tooth extraction,and with good safety,which is worthy of promotion.

Background Conjunctivochalasis (CCh) is a common age-related ocular surface diseases.Researches showed that the inflammatory factors are upregulated in conjunctiva and tear of CCh patients,inferring inflammation participates in the pathogenesis of CCh,however,its mechanism is unclear now.Studies also showed that the expression of matrix metalloproteinases (MMPs) in CCh conjunctiva is elevated.However,the association between inflammatory factors and MMPs is unknown.Objective This research was to observe the effects of tumor necrosisfactor-α (TNF-α) and interleukin-1 β (IL-1 β) on the expression of MMP-1,MMP-3,tumor necrosis factor-stimulatedgene-6(TSG-6) and pentraxin-3 (PTX3) in cultured CCh fibroblasts.Methods Conjunctival fibroblasts wereisolated and cultured from CCh-derived and cataract-derived human conjunctiva explants.The cells were treated using20 ng/ml PBS,TNF-α or IL-1β for 4 hours,respectively.The expression levels of MMP-1,MMP-3,TSG-6 and PTX3genes and proteins were detected by quantitative real time PCR and Western blot assay,respectively.Results Thesecond-generation cells showed a long and fusiform shape with ovoid nucleus and radial agreement,and the cellprocessors connected each other.The differences of the relative expression levels of MMP-1,MMP-3,TSG-6 and PTX3mRNA in the cells were significantly different between CCh group and cataract group after being treated by PBS,TNF-αand IL-1 β (MMP-1 mRNA:Fgroup =2.611,P =0.116;Fi =161.564,P =0.000;MMP-3 mRNA:Fgroup =5.201,P =0.029;Fintervene =211.021,P =0.000;TSG-6 mRNA:Fgroup =47.209,P =0.000;Fintervene =119.340,P =0.000;PTX3 mRNA:Fgroup =40.512,P =0.000;Fintervene =93.935,P =0.000).Compared with the cataract group with PBS treatment,the expression levels of MMP-1,MMP-3,TSG-6 and PTX3 mRNA were significantly elevated in the CCh group with PBS treatment or the cataract group with TNF-α and IL-1 β treatment (all at P＜0.05).Compared with the CCh group with PBS treatment,the expression levels of MMP-1,MMP-3,TSG-6 and PTX3 mRNA were significantly elevated in the CCh group with TNF-α and IL-1β treatment (all at P ＜ 0.05).The differences of the relative expression levels of MMP-1,MMP-3,TSG-6 and PTX3 proteins in the cells were significantly different between CCh group and cataract group after being treated by PBS,TNF-α and IL-1 β (MMP-1:Fgroup =84.702,P =0.000;Fint =48.900,P =0.000;MMP-3:Fgroup =112.818,P =0.000;Fint =194.980,P =0.000;TSG-6:Fgroup =56.867,P =0.000;Fint =70.356,P =0.000;PTX3:Fgroup =1.488,P =0.231;Fint =89.872,P =0.000),and the expression changes of MMP-1,MMP-3,TSG-6 and PTX3 proteins were coincident with the genes among the groups with various treatments.Conclusions The expressions of MMP-1,MMP-3,TSG-6 and PTX3 in conjunctival fibroblasts are upregulated in CCh eyes.The interaction of TNF-α and IL-1 β with MMPs is probably involved with the pathogenesis and development MMPs probably.

Objective To investigate the effects of intervertebral bridging ossifications in patients of osteoporotic vertebral compression fracture (OVCF) on bone fracture healing.Methods A total of 170 patients of thoracolumbar vertebral endplate fracture who were admitted into our hospital were selected.Divided these patients into the observation group,namely 60 patients with nonunion of vertebral endplate after 3 months of conservative treatment,and the control group, including 110 patients with well healed vertebra after 3 months of conservative treatment.Compared the distribution of intervertebral bridging ossifications of the two groups 3 weeks after injury.Results The incidence of bridging ossification at levels of T9 to T10,T10to T11,T11to T12 in the observation group were significantly higher than that in the control group.And it showed a significantly higher incidence of bridging ossification at the second proximal intervertebral segment in the observation group than that of the control group.There was a significantly greater sagittal wedge angle in the observation group compared with the control group.Conclusion Conservative treatment may increase the risk of nonunion of osteoporotic vertebral compression fractures when there is a bridging ossification at the second proximal intervertebral level or the sagittal wedge angle was greater than 14.2°in a fresh osteoporotic vertebral compression fracture.It should be a careful choose whether to take conservative treatment or surgical intervention.

Objective To observe the effect of scalp-body acupuncture plus psychological intervention in treating post-stroke depression.Method Seventy-eight patients with post-stroke depression were divided into a treatment group (40 cases) and a control group (38 cases). In addition to ordinary neurological treatments, the treatment group also received scalp-body acupuncture plus psychological intervention while the control group also received Fluoxetine hydrochloride (Prozac). The interventions were given once a day, 4 weeks as a treatment course, for 2 courses in total. Hamilton Rating Scale for Depression (HAMD) and neurological impairment severity scale (NISS) were observed before intervention, after 1 treatment course and at the end of the intervention.Result After intervention, the HAMD and NISS scores dropped significantly in both groups, and the treatment group was markedly better than the control group (P＜0.05). The total effective rates of anti-depression and recovery of neurological function in the treatment group were significantly higher than those in the control group (P＜0.05).Conclusion Scalp-body acupuncture plus psychological intervention can produce a content efficacy in improving depression and recovering neurological function.

Objective To investigate the role of three-dimensional (3D) radiotherapy to the thoracic primary tumor in non-small cell lung cancer (NSCLC) patients with bone metastases during chemotherapy with concurrent 3D radiotherapy.Methods From 2003 to 2010,the clinical data of 95 stage Ⅳ NSCLC patients with bone metastases were collected.All patients received 3D radiotherapy to the thoracic primary tumor and at least 2 cycles of chemotherapy.Of the 95 patients,47 had only bone metastases,and 48 had metastases to bones and other organs.The Kaplan-Meier method was used to calculate overall survival (OS) rates.The log-rank test was used for survival difference analysis and univariate prognostic analysis.The Cox regression model was used for multivariate prognostic analysis.Results The follow-up rate was 95％.The 1-,2-,and 3-year OS rates were 44％,17％,and 9％,respectively.The univariate analysis showed that radiation dose to the planning target volume (PTV) of primary tumor of ≥ 63 Gy,response to treatment of primary tumor,and at least 4 cycles of chemotherapy were favorable prognostic factors for OS in all patients (P =0.001,0.037,and 0.009).Radiation dose to the PTV of primary tumor of ≥ 63 Gy remained the favorable prognostic factor for OS in patients with only bone metastases and those with metastases to bones and other organs (P =0.045 and 0.012).Among patients with only bone metastases,those with T1 + T2 primary tumors had longer OS than those with T3 + T4 primary tumors (P =0.048).The multivariate analysis showed that radiation dose to the PTV of primary tumor of ≥ 63 Gy and metastases to bones only were independent favorable prognostic factors for OS in all patients (P =0.036 and 0.035).Conclusions For NSCLC patients with bone metastases,3D radiotherapy to the thoracic primary tumor and its dose play an important role in improving OS during chemotherapy with concurrent 3D radiotherapy.

OBJECTIVE:To study the effects of Clebopride(CBP)bioadhensive sustained-release tablets on experimental gas-tric ulcer and gastrointestinal motility disorder. METHODS:Gastric ulcer rat model was induced by ethanol and aspirin,and then divided into model group (normal saline),common tablet (CBP tablet 0.072 mg/kg) and sustained-release tablet high-dose and low-dose groups (CBP bioadhensive sustained-release tablet 0.072,0.036 mg/kg);normal rats were included in normal control group (normal saline);they were given relevant medicine intragastrically,twice a day for sustained-release tablet,three times a day for other. Ulcer area were observed 2 and 4 days after medication to calculate healing rate of ulcer(n=6). Gastrointestinal mo-tility disorder mice model was induced by atropine,and then divided into model group (normal saline),common tablet group (CBP tablet 0.1 mg/kg)and sustained-release tablet high-dose,medium-dose and low-dose groups(CBP bioadhensive sustained-re-lease tablet 0.1,0.05,0.025 mg/kg);normal mice were included in normal control group(normal saline);they were given rele-vant medicine intragastrically,once a day,for consecutive 3 days. The rate of gastric emptying and small intestinal propulsion were detected (n=6). RESULTS:Compared with normal control group,ulcer area of rats increased in model group;compared with model group,that of rats decreased in common tablet group and sustained-release tablet high-dose,low-dose groups,with statisti-cal significance (P<0.01);healing rates of gastric ulcer were 32.35%-48.24% 2 days after medication,and those were above 70% 4 days after medication. Compared with normal control group,the rate of gastric emptying and small intestinal propulsion in mice decreased in model group;compared with model group,those of mice increased in common tablet group and sustained-re-lease tablet high-dose,medium-dose,low-dose groups. The effects of sustained-release tablet high-dose and medium-dose groups were better than that of common tablet group;those difference had statistical significance (P<0.01 or P<0.05). CONCLU-SIONS:CBP bioadhensive sustained-release tablets have im-provement effects against gastric ulcer of rats and gastrointesti-nal motility disorder of mice.

Chemokines and chemokine receptors involve in biological activity and pathological process widely.It has been reported that many tumor cells overexpress functional chemokines.In lung cancer,chemo-kines involve in its proliferation,apoptosis,invasion and metastasis.Chemokines and chemokine receptor over-expressed in lung cancer can be used as specific target for pertinent anti-tumor treatment.
