Objective To evaluate the clinical significance of the detection of the Human Papilloma Virus (HPV) DNA typing in therapy of cervical diseases. Methods 780 cases have been studied. These cases which showed HPV-DNA positive and were diagnosed by biopsy as cervical cancer or cervical intraepithelial neoplasia( CIN Ⅰ-Ⅲ) were treated by operation or physical therapy. And 6 months and 12 months after the treatment,TCT and HPV DNA test were carried out. Results The prevalence of HPV-DNA types among the 780 cases descended from HPV 16 to 52,58,18,33 and 31. Detection rates of HPV-52 and 58 were highest among the patients with CIN Ⅰ. In patients with CIN Ⅱ,CIN Ⅲ,carcinoma in situ and invasive carcinoma,the positive rate of HPV-16 was obviously higher than other genotypes,and the difference was significant (P＜0. 01 ). 520 cases were followed-up after treatment,we found that HPV-DNA subsided within 3 months to 1 year in 432 cases. 88 cases still showed the HPV-DNA positive, among this group 48 cases were cytology diagnosed as normal or inflammation,but 14 cases were ASC-US,22 cases were LSIL and 4 cases were HSIL. Cytology abnormal cases were mere often detected in patients with persistent HPV-positive than in patients with HPV-negative. Conclusion Referring patients with cervical diseases the common HPV genotypes are 16,52,58,18,33 and 31. Especially HPV-16 are closely related with cervical cancer and high-level cervical intraepithelial neoplasis. HPV-DNA turn negative in most patients in 12 months after treatment. Persistent infection of HPV-DNA is related with the pathological changes persist.

Objective To evaluate the effect of intrathecal dexmedetomidine on the expression of G-protein-coupled inwardly rectifying K+ channel 1 (GIRK1) in dorsal root ganglia of rats with diabetic neuropathic pain (DNP).Methods A total of 144 healthy adult male SPF Sprague-Dawley rats,aged 8-10 weeks,weighing 200-220 g,were randomly divided into 4 groups (n =36 each) using a random number table:control group (group C),dexmedetomidine group (group D),group DNP,and DNP + dexmedetomidine group (group DD).DNP model was established by single intraperitoneal injection of streptozotocin (STZ) 60 mg/kg.In D and DD groups,dexmedetomidine 1.5 μg/kg was injected intrathecally at 14 days after citrate buffer or STZ injection,while the equal volume of normal saline was given in group C.The mechanical pain threshold was measured before STZ injection (T0),at 14 days after STZ injection (T1),and at 2,4 and 6 h after intrathecal injection (T:2-4).After measurement of the mechanical pain threshold at T2-4,the rats were sacrificed,and the dorsal root ganglia of the lumbar segment (L4-6) were removed for determination of the number of GIRK1 positive cells and expression of GIRK1 protein by immunofluorescence and Western blot,respectively.Results Compared with group DNP,the mechanical pain threshold was significantly increased,the number of GIRK1 positive cells in dorsal root ganglia was significantly increased,and the expression of GIRK1 was significantly up-regulated at T2-4 in group DD (P＜0.05).Compared with group D,the number of GIRK1 positive cells in dorsal root ganglia was significantly increased,and the expression of GIRK1 was significantly up-regulated at T2-4 in group DD (P＜0.05).Compared with group C,the mechanical pain threshold was significantly decreased at T1-4 in group DNP (P＜0.05).Conclusion Intrathecal dexmedetomidine attenuates DNP through up-regulating the expression of GIRK1 in dorsal root ganglia of rats.

ObjectiveTo explore the changes of the levels of cytokines in patients with first-episode depression and the effect on the levels of cytokines after the treatment with duloxetine.MethodsThe serum levels of interleukin 1 ( IL-1 ),interleukin 6 ( IL-6 ),tumor necrosis factor-alpha ( TNF-αt ),interleukin4 ( IL-4 ),interleukin10(IL-10) were measured in 38 patients with depression before and after duloxetine treatment by enzyme linked immunosorbent assay(ELISA).HAMD score were assessed at pre- treatment and post-treatment to assess curative effect.The control group was 30 healthy individuals.All data were statisticaly analyzed by SPSS.ResultsBefore treatment,the HAMD score and the levels of serum IL-6,TNF-α,IL-1 in first-episode depressant patients were remarkablely higher than those in the control group( IL-6:( 10.66 ± 3.12 ) pg/ml vs (2.72 ± 0.91 ) pg/ml ;TNF-α:(77.49 ±3.12) pg/ml vs (37.48 ±5.87) pg/ml; IL-1:(39.09 ± 3.77 ) pg/ml vs ( 10.31 ± 1.05 ) pg/ml ),the levels of serum IL-4 and IL-10 in first-episode depressant patients were remarkablely lower than those in the control group(P＜0.05,P＜0.01 ).The HAMD score and the levels of serum IL-6,TNF-α,IL-1 in post-treatment were remarkablely lower than pre-treatment (P ＜ 0.05 ),but which were still higher than the control group(P＜ 0.05 ).The levels of serum IL-4 and IL-10 in post-treatment were remarkablely increased than pre-treatment(P＜0.05).The levels of serum IL-6,TNF-α,IL-1 were positively correlated with the HAMD score( r =0.667,0.486,0.727,P ＜0.01 ),but the levels of serum IL-4 and IL-10 were negatively correlated with the HAMD scorae ( r=-0.433,-0.269,P＜0.05,P＜ 0.01 ).ConclusionsThe first-episode depressant patients show immune disorder induced by cytokines.Anti-depressant activity of duloxetine may participate in the regulation of cytokines and Th1/Th2 unbalance.

Objective To use evidence-based nursing on patients with artificial airway to the practice of stomach tube, and to evaluate the self made guidance for difficult gastric tube placement in patients with artificial airway.Methods Forty patients with artificial airway and were difficult to put the tube, and admitted to Department of Critical Care Medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University from April to December in 2016 were enrolled as observation group. Through the evidence-based nursing strategy, the related literatures at home and abroad were collected to search clinical evidence and formulate and implement the nursing program, the gastric tube was inserted into the stomach tube under the direct vision of the laryngoscope. Thirty-six patients of difficult gastric tube placement with artificial airway straightly under the direct vision of the laryngoscope from August 2015 to March 2016 were retrospectively analyzed as the control group. The success rate of first catheterization, indwelling time, throat edema and bleeding of pharyngeal mucosa were compared between the two groups.Results All patients were enrolled in the final analysis. In the control group, 28 patients were successfully placed once, while 8 failed. Only 1 patient in observation group failed to catheterize, and successful placed after symptomatic treatment, the one-time success rate of catheter was significantly higher than that of control group (97.5% vs. 77.8%), and catheter time was significantly shortened (minutes: 4.8±1.2 vs. 5.1±1.0), the difference was statistically significant (bothP < 0.05). There were 2 patients with laryngeal edema in the control group and 4 patients of pharyngeal mucosal hemorrhage. In the observation group, there was no laryngealedema and laryngeal edema occurred in the patients with laryngoscopy, and only 1 patient had a hemorrhage of pharyngeal mucosa.Conclusion Using self made guiding device can effectively insert the difficult gastric tube in patients with artificial airway, and increase the one-time success rate of intubation, shorten the catheter time, and have a trend in reduce complication as compared with traditional gastric tube placement.

Objective To explore the clinical effect and toxicity of daunorubicin combined with cytarabine (DA regimen) and idarubicin combined with cytarabine (IA regimen) for the treatment of patients with acute myeloid leukemia (AML) as induction chemotherapy. Methods The clinical data of 84 newly diagnosed AML patients (except M3) treated with DA or IA regimen were analyzed retrospectively. DA regimen group included 32 patients (17 males and 15 females with median age of 46 years), while IA regimen group included 52 patients (29 males and 23 females with media age of 49 years). Efficacy index was complete remission (CR), total efficiency and adverse reactions after one course of chemotherapy rate. Results In DA regimen group,the CR rate was 65.6 %(21/32), and the total efficiency rate was 75.0 %(24/32), while in IA regimen group, the CR rate was 71.2 %(31/52), and the total efficiency rate was 80.8 %(42/52), respectively, but, the differences of media survival and 5-year survival rate were not statistically significant (16.8 months vs. 24.9 months, 26 % vs. 44 %, both P>0.05). The main side effect in the two groups included hematologic (bone marrow suppression) and non-hematologic adverse reactions, with no significant difference between the two groups (all P>0.05). Conclusion For newly diagnosed AML patients, remission rate and total efficiency of DA regimen are same as IA regimen after one course treatment, and adverse events between the two regimens do not differ significantly.
