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.

Objective To analyze the clinical prevalence,distributed characteristic of different ages,clinical characteristics and pathogenic factors of chronic abdominal pain in children.Methods A database in which outpa-tient and inpatient of abdominal pain during 2 -14 years old were collected from January 2011 to December 2015 was established by utilizing HIS system.A statistical analysis was made in age,sex,onset time,time of duration,mesenteric lymph node status and surgical situation.Results A total of 13 256 times abdominalgia were enrolled from January 2011 to December 2015.7 390 patients were diagnosed as unexplained abdominal pain,including 1 005 patients (13.59%)were diagnosed as chronic abdominal pain.A male -to -female ratio was 1.06:1.The average age was 6 years(ranged 2 -14 years).The average age of the boys was (6.02 ±2.87)years,which of the girls was (5.93 ± 2.79)years,there was no statistically significant difference between them(t =0.47,P =0.63).The peak age of chro-nic abdominal pain in children was mainly from 3 to 7 years old.The incidence decreased with age increased.The average time of duration was (16.70 ±11.69)months,that of the boys was (17.39 ±12.12)months,and that of the girls was (15.96 ±11.19)months,there was statistically significant difference between them(t =1.93,P =0.05). Mesenteric lymphadenectasis was detected in 731 patients(72.74%).The age constituent ratio decreased with age increased.The peak age of the prevalence coincided with peak age of the mesenteric lymphadenectasis.21 patients underwent surgical procedures,organic lesions accounted for 2.08%.Conclusion The peak age of the prevalence of chronic abdominal pain in children is mainly from 3 to 7 years old.Potential organic causes are rarely linked to chronic abdominal pain in children.Most of them are functional abdominal pain.The appendix and mesenteric lymphadenecta-sis might play an important role in children with chronic abdominal pain.The therapeutic aim of CAP in children is to make the children back to their normal life by exclude the organic causes and relieve their pain.The natural history of chronic abdominal pain suggests that symptoms remit spontaneously with increasing age.

Objective To obtain a stably inherited Sprague-Dawley rat model of congenital umbilical hernia by in-breeding, and to observe the structure of umbilical hernia and treat it surgically.Methods Congenital umbilical hernia rats were fostered by full-sib mating.The birth number and umbilical hernia quantity were recorded, and the umbilical hernia rate of rats was analyzed.Six female and 6 male rats with congenital umbilical hernia of 6-month aged F2 generation were selected randomly, among which 2 female and 2 male rats were examined anatomically, and the rest rats underwent surgical suture. Results The umbilical hernia rate was increased along with the increasing inbreeding coefficient, and the rats of F12 and F13 generations were all with congenital umbilical hernia.The umbilical hernia rate in female rats was significantly higher than that in male rats based on the total number of rats from F1 to F13 generation (c2 =11.1, P=0.001).Female and male rats had the same structure of umbilical hernia, and all rats recovered 3-4 weeks after surgery without recurrence.Conclusion After 13 consecutive generations of full-sib mating, a rat model of congenital umbilical hernia with stable genetic properties is successfully established.

EGR-1 can promote the mRNA and protein expressions of p65 in TaxP cells, the activity of NF-κB was up-regulated by EGR-1 too. Conclusion EGR-1 maybe involve in adult T-cell leukemia(ATL) by increasing the activation of NF-κB.

Objective To evaluate the effects of intra-aortic balloon counterpulsation (IABP) on mortality of patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI).Methods Randomized controlled trials (RCTs) of IABP compared with non-IABP control in AMI patients, from January 1970 to May 2015, were searched from MEDLINE, Embase and Web of Science.The data were analyzed with software RevMan 5.0.Results Five RCTs involving 1 450 AMI patients, including 722 treated with IABP (IABP group) and 728 without IABP (non-IABP group), were included for analysis.Compared with non-IABP group, IABP did not significantly decrease the hospital mortality or 30-day mortality (OR=0.92, 95%CI: 0.69-1.25,P=0.61).According to the timing of IABP before or after PCI, it was further divided into IABP-before-PCI subgroup and IABP-after-PCI subgroup.Compared with non-IABP group, the 30-day mortality was not decreased in IABP-before-PCI subgroup or in IABP-after-PCI subgroup (OR=0.64, 95%CI: 0.23-1.78,P=0.39;OR=1.25, 95%CI: 0.42-3.77,P=0.69, respectively).According to complicating with cardiogenic shock (CS) or not, patients were divided to AMI with CS subgroup and AMI with no-CS subgroup;the hospital or 30-day mortality were not significantly decreased in both subgroups (OR=0.96, 95%CI: 0.70-1.32,P=0.80;OR=0.68, 95%CI: 0.28-1.70,P=0.27, respectively).Conclusion IABP does not decrease the 30-day mortality of AMI patients treated with PCI.

The incidence of solitary fibroma of seminal vesicle is low, and the source of seminal vesicle is rare. A 38-year-old patient was admitted to hospital because of intermittent gross hematuria for more than one month. Seminal vesicle space occupying lesions can be seen in pelvic MRI. Laparoscopic resection of right seminal vesicle tumor was performed, and the pathological diagnosis tended to solitary fibroma. During the 5-month follow-up, the symptoms of hematuria disappeared and no recurrence.

Objective To evaluate the long-term clinical efficacy and toxicities of combined intracavitary hyperthermia and radiotherapy fur locally advanced uterine cervical cancer. Methods 310 patients with locally advanced uterine cervical cancer were assigned into intracavitary hyperthermia + radiotherapy group(TRT, 181 patients) and external-beam radiotherapy + traditional intracavitary radiation group (RT,129 patients). The external-beam radiotherapy were given with 60Co γ-my or 6-8 MV X-ray in traditional fractionation. In TRT group,radiotherapy was 40 Gy using the anterior-posterior pelvic fields and additional 20-25 Gy using the lateral fields. Hyperthermia was delivered by the 915 MHz microwave hyperthermia device within 15-60 min after external radiotherapy for 10-12 times(40 min each time,1-2 times per week). The temperature of tumor surface was 46-47℃. In the RT group, the external-beam radiotherapy of 40 Gy was delivered using the anterior-posterior pelvic fields. The intracavity radiotherapy of radium was delivered before 1989 ,with 50 mg radium in the vagina and 30 mg in uterine cavity for 24 hours ,weekly for 3 times to a total dose of 7200 mg·h. After 1989,intraeavity radiotherapy of 192Ir was delivered to a total dose of 30-36 Gy to point A in 5-6 Gy fractions,2 fractions per week. Results The 5-year survival of patients in TRT group and RT group was 67.4% versus 52.1% for stage Ⅱ disease (χ2=7.55,P=0.006), and 60.0% vemus32.3% forstage Ⅲ (χ2=7.06,P=0.007) . The 10-year survival was46.5% versus42.6% for stage Ⅱ (χ2=3.90,P=0.058), and 43.7% versus 20.6% for stage Ⅲ(χ2=17.28,P=0.000). Cox regression analysis showed that the tumor stage(P=0.023) and intracavitary hyperthermia( P=0.019) were prognostic factors. According to the RTOG criteria, the rate of mild to moderate late side effects of rectum and bladder in TRT and RT group was 17.7% and 33.1%, respectively (χ2=9.18, P=0.002). Rectovaginal fistula was developed in5 patients(3.9% ) in RT group and I patient (0.6%) in TRT group(χ2= 4.38,P=0.036). Conclusions The long-term survival of patients with stage Ⅲ uterine cervical cancer is better of TRT group than RT group. The TRT is well tolerated and the late toxicity rate is obviously low. It is necessary to carry out large randomized clinical trials to confirm these outcomes.

Objective To establishing an immortal cell line of familial papillary thyroid carcinoma (FPTC), and explore a new approach for studying familial non-medullary thyroid carcinoma (FNMTC). Methods The specimen from a patient with FPTC was selected, separated, and the primary cells were cultured using DMEM/F12 medium (with TSH, T3, EGF and hydrocortisone). To inducing cell immortalization, the exogenous genes SV40T/TERT were transfected into cells by two ways. RT-PCR was used to detect the expressions of thyroid peroxidase (TPO), thyroid globulin (TG), thyroid stimulating hormone receptor (TSHR) and sodium/iodide co-transporter (NIS). Immunofluorescence method was used to detect the expressions of TPO and GPC3. In order to detect the genomic mutations, the peripheral blood DNA of the patient was extracted. The cell genome was detected. Results The FPTC cells adhered to the plate and showed an irregular polygon shape. The cells can stably grow for six months, FPTC-S (with SV40T transfected) passaged to p26, FPTC cells passaged to p23 and FPTC-ST (with SV40T/TERT transfected) passaged to p19. Both FPTC-S and FPTC-ST can stably express TPO, TG and TSHR in mRNA level. MLH1 R217C mutation existed in the peripheral blood of the patient, and BRAF V600E mutation existed in the primary cultured cells. Either the primary or the immortal cells showed MLH1 R217C mutation. Conclusion This study preliminarily established an immortal cell line of familial papillary thyroid carcinoma with MLH 1 R217C and BRAF V600E mutations. This cell line provides a research model for studying these mutations in FPTC.

OBJECTIVE: To explore the association of Ezrin and E-cadherin expression with the invasion, metastasis and prognois of nasopharyngeal carcinoma. METHODS: Imunohistochemical SP staining was used to detect the expression of Ezrin and E-cadherin in 42 nasopharyngeal carcinoma and 10 chronic nasopharyngitis specimens. RESULTS: Ezrin protein expression in the nasopharyngeal carcinoma tissues was significantly higher than that in the chronic nasopharyngitis tissues (P<0.05). E-cadherin expression in the nasopharyngeal carcinoma tissues was significantly lower than that in the chronic nasopharyngitis tissues (P<0.05). Expressions of both Ezrin and E-cadherin of nasopharyngeal carcinoma were closely associated with T staging,the cervical lymph node metastases and clinical staging (P<0.05). A negative correlation was found between Ezrin and E-cadherin expression in the nasopharyngeal carcinoma tissues (r=-0.450, P<0.05). Survival analysis showed that the abnormal expression of Ezrin and E-cadhrin, clinical staging and the cervical lymph node metastases were associated with the survival rate of patients with nasopharyngeal carcinoma. CONCLUSION A negative correlation is found between Ezrin and E-cadherin expression in the nasopharyngeal carcinoma tissues. Ezrin and E-cadherin are closely related to clinical staging and the cervical lymph node metastases of nasopharyngeal carcinoma,suggesting that they may be important tumor markers for nasopharyngeal carcinoma. Combined detection of the expressions of Ezrin and E-cadherin is helpful for clinical doctors to determine the prognosis of patients with nasopharyngeal carcinoma.
