Objective To introduce a new septorhinoplastic method for twisted nose, humped nose and hawk nose as well as deviation of nasal septum, and to evaluate its operative method and effect. Methods The incision of cleft between lateral nasal cartilage and greater alar cartilage was employed in all patients. The method of unilateral mucoperiosteal flap osteotomy was used to correct nasal pyramid deformity, and swinging-door operation was performed to correct the deviation of nasal septum simultaneously. Results The operative results of 36 cases were effective and satisfactory. Postoperative follow-up ranged from one year to fifteen years. Based on the results of follow-up in the 32 cases, no recurrence and complications were found in all the cases. Conclusion This new method for septorhinoplasty avoids the detachment and move of nasal bone and nasal septum cartilage and injury of nasal mucoperiosteum, and maintains the blood supply of nasal bone and nasal septum cartilage. It corrects extero-nasal deformity as well as deviation of nasal septum. The operation is effective in nose aesthetic and ventilatory function.

Objective To determine whether sulfasalazine stimulates hepatic stellate cell (HSC-T6) apoptosis and its possible mechanism. Methods CCK-8 assay, acridine orange/ethidium bromide(AO/EB) and Annexin Ⅴ FITC/PI were used to determine cell growth and cell apoptosis. The expression of NF-?B P65, phospho-IKK and phospho-I?B was detected by Western blotting. The nuclear translocation of HSC-T6 P65 was observed with laser confocal microscopy. Results Sulfasalazine displayed a strong growth inhibition and promoting apoptosis effect on HSC-T6 cells in a dose and time-dependent manner. Sulfasalazine, but not 5-aminosalicylic acid or sulfapyridine, inhibited the activation of NF-?B by down-regulating the expressions of P-IKK, P-I?B and the nuclear translocation of P65. Conclusion Sulfasalazine can inhibit NF-?B activity and promote apoptosis in HSC-T6 cells, where the Rel/NF-?B/I?B/IKK pathway plays an important role in HSC survival.

Objective To study the effect of whole-process nursing intervention on comfort of patients undergoing radial artery puncture. Methods 100 patients with radial artery puncture from July, 2007 to June, 2008 were divided into the control group and the experimental group with 50 cases in each group accord-ing to time sequence. Routine whole nursing mode was used in the control group, the whole-process nursing intervention mode based upon routine nursing mode under the instruction of evidence-based method was used in the experimental group. Pain, psychological tensity, body numbness, success rate of radial artery puncture, patients' satisfaction degree were compared between the two groups. Results Every indexes of the experi-mental group were better than those of the control group. Conclusions The whole-process nursing interven-tion mode can promote the comfort degree of patients undergoing radial artery puncture.

Objective To analyze the suspicious results of serum HBV DNA by fluorescence quantitative PCR and develop appropriate countermeasures in order to improve the quality of detection of HBV DNA.Methods Blood samples of patients from the First Affiliated Hospital of Wenzhou Medical College from 2008 to 2011 were analyzed for HBV DNA by fluorescence quantitative PCR.1969 cases of suspicious results,judged by the rule of review the results of serum HBV DNA combined with the historical results,PCR amplification curve,HBV serum markers and clinical diagnosis,were analyzed and redetected by using of two different reagents,careHBV PCR Kit and careHBV PCR Kit V2,at the same time.The consistency and inconsistency ratio of the results were evaluated.Both the reasons of inconsistent and the undetected rates of careHBV PCR Kit were analyzed.The two reasons for the inconsistent results included the reagent related factors,e.g,showing no amplification curve caused by the false negative and abnormal low efficiency of amplification curve,and the non reagent related factors such as operating pollution and other sample factors.Results There were 115 154 blood samples were detected for HBV from 2008 to 2011 and 1969 samples (1.71％) with suspicious results were redetected.The consistency and inconsistency results were 1588 (80.65％) and 381 (19.35％),respectively.Every year from 2008 to 2011,the percentage of the inconsistent results caused by the reagent related factors were 18.87％,20.23％,51.33％ and 59.57％ respectively,which showed an increasing trend,and the percentage of inconsistent results caused by the nonreagent related factors were 81.13％,79.77％,48.67％ and 40.43％ respectively,which showed a declining trend year by year.The undetected rates of careHBV PCR Kit were 2.49％,4.08％,10.09％ and 14.47％ respectively,showing an increasing trend.Conclusions The redetection for the specimens with the suspicious results by using of different reagents can avoid the blind detection of HBV DNA and reduce the experimental error.All the clinical samples for quantitative HBV DNA including the mutations of HBV gene can be measured accurately and effectively,which is helpful to hepatitis B patients for antiviral therapy.

Objective To discuss the clinical efficacy of surgery for chronic subdural hematoma assisted by rigid neuroendoscope and its surgical techniques. Methods Clinical data of 161 patients with chronic subdural hematoma from August 2009 to December 2015 was analyzed retrospectively. 74 of them experienced surgeries assisted by rigid neuroendoscope (endoscope group) and other 87 cases were operated without neuroendoscope (routine group) during the same period. Results Although there were significant difference in operative duration between the two groups, complications, ratio of total removal of hematoma after surgery, postoperative inpatient duration and recurrent rate of hematoma were more advantageous in endoscope group. The operative duration of endoscope group with (112.68 ± 34.86) min was longer than that of routine group with (74.11 ± 28.23) min (t = 7.75, P = 0.000), while the postoperative inpatient duration of endoscope group with (8.23 ± 2.01) d was shorter than that of another group with (10.79 ± 5.02) d (t = -4.12, P = 0.000). There were no surgical associated complications in endoscope group, but 1 patient in routine group experienced intracerebral hematoma of frontal lobe and associated aphemia. Total removal of hematoma was confirmed in endoscope group with 98.65% (73/74), which was higher than that in routine group with 86.21% (75/78) (χ2 = 8.34, P = 0.004). Hematoma recurrence was found in 16 cases of routine group (18.39%), but more superiority in endoscope group with 1.35% (χ2 = 12.29, P = 0.000). Outpatient follow-up was carried out in all patients from 6 to 38 months with an average duration of 30.06 months. In 17 cases with recurrent hematoma during follow-up, 15 of them were cured by a second surgery, and another 2 patients were cured by atorvastatin. Conclusion As a simple, safe and effective technique, the application of rigid neuroendoscope during surgery for chronic subdural hematoma is more advantage than routine surgery. A self-made suction with adjustable soft curved tip is suitable for such procedure.

Objective To analyze the expression of T lymphocyte activation antigen in peripheral blood of aged patients with non-small cell lung cancer . Methods The lymphocytes from peripheral blood in 45 aged patients with non-small cell lung cancer were immunologically labeled in double fluorescence and CD3-FITC, CD25/HLA-DR and CD69-PE and determined by flow cytometry. Normal aged donors, young patiens with lung cancer and aged benign lesion group were used as controls. Results Peripheral blood CD3 +/CD25 +, CD3 +/HLA -DR + and CD3 +/CD69 + in T lymphocyte with 45 aged lung cancer(7.24?1.85,28.46?5.39 and 7.78?2.63, respectively) were significantly lower than those in normal aged controls(10.35?2.54,37.16?5.51,11.02?2.18, respectively)and aged benign lesion (9.53?3.02, 35.33?5.23, 10.67?2.45, respectively)( P 0.05). Significant differences were found among them in stages Ⅲ, Ⅳ(7.15?1.13, 25.32?5.23, 7.14?2.81, respectively) and stagesⅠ,Ⅱ(8.06?1.21, 30.27?6.05, 8.43?2.67, respectively)( P 0.05). Conclusions Detection of CD3 +/CD25 +, CD3 +/HLA -DR + and CD3 +/CD69 + levels by flow cytometry might be helpful for reflecting the human immune function and the prognosis evaluation in patients with aged non-small cell lung cancer.

Objective To study the genotypes of OXA-51-like carbepenemases in Aeinetobacter beumannii and its association with drug resistance. Methods The susceptibility of 174 Acinetobacter baumannii against ceftazidime, cefotriaxon, amikacin and ciprofloxacin were detected with disc diffusion method. The minimum inhibitory concentration (MIC) values for meropenem and imipenem were determined with an agar dilution method. VIM, IMP, OXA-23, OXA-24, OXA-51 and OXA-58 β-lactamase genes were determined by PCR. DNA sequencing and genotyping were performed against OXA-51 positivestrains. Results All 174 isolates were negative by PCR for genes OXA-24, OXA-58, IMP and VIM. OXA-23 and OXA-51were amplified in 15.5% (27/174) and 72.4% (126/174) isolates, respectively. Therewere 15.5% (27/174) isolates producing OXA-51-like and OXA-23 carbapenemase simultaneously. Among126 OXA-51-like carbapenemase producing strains, 82.5% (104/126)were OXA-66 genotype, whereas theremaining 17.5% (22/126) strains belong to other genotype. Eight novel OXA-51-like Genotype were foundin this study. Conclusions OXA-66 were the primary genotype of OXA-51-like carbapenemases in A.baumannii. OXA-66 were related to low-level carbapenems resistance and may be associated with resistanceof other drugs. We found new OXA-51-like genotype in clinic isolates of A. baumannii in this study.

ObjectiveTo study the therapeutic effects of cerebellar fastigial nucleus electrical stimulation (FNS) on motor and depression symptoms and monoamine neurotransmitters in the spinal cord fluid of patients with Parkinson's disease (PD).Methods65 patients with idiopathic Parkinson's disease following depression were divided into stimulation group (FNS+Madopar, n=35) and control group (Madopar, n=30). The stimulation group took Modopar, and treated with FNS, 30 miniutes once a day for 30 days. The control group took Modopar only. Madopar dose has no change during the treatment. The patients were evaluated by Webster Parkinson's Disease Evaluation Form, and Hamilton Depression Scale (HAMD) before and after FNS treatment. The loading of monoamine neurotransmitters was measured by high performance liquid chromatography-electrochemical process.ResultsAfter the treatment, the stimulation group improved in clinical feature and depression, scored significantly lower on Webster and HAMD than the control group(P<0.05); the loading of 5-hydroxytryptamine(5-HT) in spinal cord fluid increased; however noradrenalin and dopamine had no different. But there was no significant change in the symptoms and the loading of monoamine neurotransmitters in the control group.ConclusionFNS is efficient to relieve the motor and depression symptoms of PD, which possible mechamism might be central neuroprotection and the release of 5-HT by FNS induction.

Objective To explore the therapeutic effect of hydrocephalus after moderate and severe brain injury with ventricle-peritoneum shunt(VPS). Methods The clinical data of 42 cases with post-traumatic hydrocephalus admitted in our hospital were analyzed retrospectively.Results The patients' consciousness and nerve function had been improved, including 22 cases (52.4%) of good recovery, 12 cases (28.6%) of moderate deficit, 8 cases(19.0%) medially disabled and severely disabled. There was no operative mortality. Conclusion VPS can improve patients consciousness and nerve function and outcome with hydrocephalus after trauma,and reduce the mortality and disability rate of severe brain injury.

BACKGROUNDTo investigate the expression feature of Cx43 protein in non-small cell lung cancer and its clinical significance.

METHODSParaffin embedded tissues from 65 patients with primary non-small cell lung cancer and 20 adjacent non-cancerous lung tissues were investigated for expression of Cx43 protein by immunohistochemistry (ABC method). The relationship between Cx43 protein expression and clinicopathological characteristics of lung cancer was analyzed.

RESULTSCx43 protein was positively expressed in 24 out of 65 lung cancer tissues (36.92%), and in all 20 adjacent non-cancerous lung tissues. There was a significant difference in Cx43 expression between stage I-II and stage III-IV groups ( P < 0.05), as well as between moderate-well and poor differentiation groups ( P < 0.01). Primary lung cancer tissues with lymph node metastasis showed lower expression of Cx43 than those without lymph node metastasis ( P < 0.01). The positive rate of Cx43 expression was not related to histological classification ( P > 0.05).

CONCLUSIONSCx43 expression might play a role in the genesis, development and metastasis of lung cancer. It may be used to judge the biological behavior of lung cancer.
