Objective To evaluate the effect of heart rate control with esmolol on hemodynamics, inflammatory cytokines and clinical outcomes in patients with septic shock.Methods A prospective randomized controlled trial was conducted. The patients with septic shock admitted to Department of Critical Care Medicine of China-Japan Friendship Hospital from August 2014 to October 2016 were enrolled. After 24 hours of resuscitation and other therapy, they were randomly divided into two groups by sealed envelope. The patients in experimental group was treated with continuous intravenous esmolol infusion for 24 hours, initial dose was 0.05 mg·kg-1·h-1, and was titrated to decrease the heart rate by 20% as compared with the value at the time of enrollment or below 95 bpm, while isotonicsaline was given to control group through intravenous line at 3 mL/h for 24 hours. The differences in hemodynamic parameters at 0, 1, 4, 8, 12, 24 and 48 hours, as well as serum inflammatory cytokines and blood lactate (Lac) at 0, 12, and 24 hours, 28-day mortality were compared between the two groups.Results Seventy-six septic shock patients were admitted during the study, 12 were excluded forsuspicious acute myocardial infraction (AMI) or acute left heart failure or for the history of chronic obstructive pulmonary disease (COPD), 4 were quitted the study for being unable to tolerate the lowest dose of esmolol, giving up treatment, or death within 24 hours. Finally, 60 patients completed the study, 30 patients in experimental group, and 30 in control group. There were no differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and infection source between two groups, indicating the general data between the two groups were balanced and comparable. The decrease in heart rate was more markedly in experimental group than that of control group at 1, 4, 48 hours after esmolol administration (bpm: 97.4±16.5 vs. 110.9±19.6, 95.2±15.3 vs. 105.1±17.9, 86.4±12.1 vs. 97.2±22.6, allP < 0.05), cardiac index (CI) at 8, 24, 48 hours was significantly increased(mL·s-1·m-2: 57.2±13.5 vs. 46.5±11.0, 57.7±15.7 vs. 48.7±14.7, 61.2±16.5 vs. 51.5±14.7, allP < 0.05), and stroke volume index (SVI) at 4, 8, 24 hours was significantly increased (mL/m2: 34.1±6.9 vs. 29.0±8.7, 35.0±6.1 vs. 28.8±9.6, 38.3±10.1 vs. 31.9±13.2, allP < 0.05). Interleukin-1β (IL-1β) at 24 hours in experimental group was significantly higher than that of control group (ng/L: 0.15±0.06 vs. 0.13±0.05,P < 0.01). There were no differences in mean arterial pressure (MAP), Lac, white blood cell (WBC), IL-6, IL-10, and tumor necrosis factor-α (TNF-α) between the two groups, and no difference in 28-day mortality between experimental group and control group was found (30.0% vs. 36.7%,χ2 = 0.300,P = 0.583).Conclusions It is efficient and safe to use esmolol for heart rate control in patients with septic shock after resuscitation. Esmolol can improve cardiac performance without affecting blood pressure and Lac, but has no effect on inflammatory cytokines and prognosis.

Objective To explore the effect of nucleos(t)ide analog (NA)antiviral treatment on the pathological differentiation of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC)and the prognostic factors of HCC.Methods Totally 127 patients with HBV-related HCC who were hospitalized and received partial hepatectomy in First Affiliated Hospital of Harbin Medical University from March 2007 to November 2013 were included in this study.Sixteen cases received antiviral treatment before operation and the remaining 111 cases had no history of NA treatment.The differences of histopathological grading were compared between the two groups.Twenty-nine patients received antiviral treatment for the first time after surgery,and the rest 82 patients did not.All these patients were followed up for survival and recurrence.Multivariate analysis was used to explore the prognostic factors for HCC.The categorical variables were analyzed byχ2 test or Fisher exact test.Survival rate was compared with Log-rank test. Univariate or multivariate Cox regression analysis was used to explore the related factors of survival. Results The proportions of well-,moderately- or poorly-differentiated HCC in patients with antiviral treatment before surgery were 18.75 %,68.75 % and 12.5 %,respectively.Whereas the proportions in those without treatment were 16.22%,66.67% and 17.11 %,respectively.There was no significant difference in histopathological grading of HCC between the two groups (χ2=0.224,P =0.885 ).The overall median survival time was 39 months.The 6-month,1-and 2-year survival rates were 91 .7%, 77.5 % and 59.3%,respectively.The 6-month,1- and 2-year survival rate of postoperative antiviral treatment were 96.3%,92.4% and 78.5 %,respectively,which were significantly higher than those of no antiviral treatment group (85 .9%,70.0% and 48.5 %,respectively;χ2= 6.967,P = 0.008 ). Univariate analysis showed that tumor number,size,portal vein transfer,AFP level,postoperative antiviral treatment,histopathological grading,TNM staging,BCLC staging,γ-GT and PTA were prognostic factors for postoperative HCC survival.Multivariate analysis showed that AFP level (HR=1 , 95 %CI :1 .0004—1 .002,P =0.004),postoperative antiviral treatment (HR =0.38,95 %CI :0.38—0.15 ,P =0.04)and BCLC stage (B vs A:HR=1 .55 ,95 %CI :0.76—3.18;C vs A:HR=3.63,95 %CI :1 .31 —10.09,P =0.04)were independent prognostic factors.Conclusions Preoperative antiviral treatment has no impact on the histopathological grading of HCC. BCLC stage, AFP level and postoperative antiviral treatment are independent prognostic factors for HBV-related HCC.

Objective To investigate the efficacy of breast tissue flap cohesive treatment after breast augmentation injection mixture dis-placed.Methods A total of 78 patients with breast augmentation injection mixture polyacrylamide hydrogel(PAAG)shift in our hospital from January 2006 to March 2014 were divided into two groups according to different surgical methods,39 cases with the material shifted to abdominal wall in control group were treated by taking the cleaning operation to scrape residual cavity,39 patients in observation recieved new breast tissue flap design local treatment of breast fistula closed chest and abdominal wall channel after surgical elimination of the same abdom-inal wall cavities.Results The PAAG extensive deposition in the breast tissue,armpits,chest wall clearance were formed fistula communica-tion.The secretions of patients treated with tissue flap decreased 82%,the lacunar lesions reduced 80% after 2 weeks,while patients without tissue flap,the drain reduced 46%,the lesion size reduced 45%,the difference between the two groups was significant(P <0.01).The heal-ing rate of tissue flap group was higher than that of conventional group after 4 weeks.Conclusion The PAAG mixture shifting formed fistula communication in the abdominal wall is the main reason of the mass flow and a huge cavity.Flap can significantly promote abdominal wall fis-tula healing.

OBJECTIVE: To investigate the effects of radioactive ray on transmission capability of nose mucociliary. METHOD: Forty-six patients with NPC were selected and saccharin clearance time (SCT) for 7 phases were detected in both pre- and post-radiotherapy respectively. RESULT: Among 46 patients with NPC, the shortest SCT was 247 seconds and the longest 601 seconds in pre-radiotherapy phases; from 4th week of introradiotherapy to 18 months of postradiotherapy, the longest SCT was in 12 months after radiotherapy, which was 903 seconds. There were no significant differences in SCT before radiotherapy and 18 months after radiotherapy. There were significant differences in SCT of preradiotherapy and introdiotherapy, post radiotherapy, after radiotherapy 3 months, 6 months, 12 months after radiotherapy. CONCLUSION Radiotherapy is the important factors in influencing transmission capability of nose cavity and sinus mucociliary and hints that gender and nasal cavity side don't affect SCT. Detection of SCT in different stages of NPC patients can be helpful to protect nasal mucous membrane effectively, and to reduce incidence rate of RNS.

Objective: To investigate the positive rate for 2019-nCoV tests and co-infections in Wuhan district. Methods: A total of 8 274 cases in Wuhan were enrolled in this cross-sectional study during January 20 to February 9, 2020, and were tested for 2019-nCoV using fluorescence quantitative PCR. Both respiratory tract samples (nasopharynx, oropharynx, sputum and alveolar lavage fluid) and non-respiratory tract samples (urine, feces, anal swabs, blood and conjunctival sac swabs) were collected. If both orf1ab and N genes are positive, they are classified as nucleic acid test positive group; if both orf1ab and N genes are negative, they are classified as negative group; if single gene target is positive, they are classified as suspicious group. Individuals were divided into male group and female group according to sex. At the same time, 316 patients were tested for 13 respiratory pathogens by multiplex PCR. Results: Among the 8 274 subjects, 2 745 (33.2%) were 2019-nCoV infected; 5 277 (63.8%) subjects showed negative results in the 2019-nCoV nucleic acid test; and 252 cases (3.05%) was not definitive (inconclusive result). The age of cases with COVID-19 patients and inconclusive cases was significantly higher than that of cases without 2019-nCoV infection (40 vs 56, t=27.569, P<0.001; 52 vs 56, t=6.774, P<0.001). The positive rate of 13 respiratory pathogens multiple tests was significantly lower in 104 subjects who were positive for 2019-nCoV compared with those in subjects who were negative for 2019-nCoV test (5.77% vs 18.39%, χ²=24.105, P=0.003). Four types of respiratory tract samples and five types of non-respiratory tract samples were found to be positive for 2019-nCoV nucleic acid test. Conclusion The 2019-nCoV nucleic acid positive rate in male is higher than in female. Co-infections should be pay close attention in COVID-19 patients. 2019-nCoV nucleic acid can be detected in non-respiratory tract samples.
