Objective To study on the correlation of hepatic fibrosis with angiotensin Ⅱ (Ang Ⅱ ) in the hepatitis B patients . Methods The electrochemical luminescence and the rate method were adopted to detect hyaluronidase (HA) and Ang Ⅱ levels in 92 cases of acute hepatitis B (acute group) ,108 cases of chronic hepatitis B(chronic group) and 50 healthy people(control group) , and the detected results were performed the correlation analysis .Results Compared with the acute group and the control group ,the HA and Ang Ⅱ levels in the chronic group were increased significantly (P<0 .05) .The HA and Ang Ⅱ levels had statistical differ-ence between the acute group and the control group (P<0 .05) .Further analysis showed that there was a positive correlation be-tween HA and Ang Ⅱ levels(r=0 .629 ,P<0 .05) .Conclusion There the HA level is closely related with the Ang Ⅱ level ,and both of them participate in the process of liver fibrosis ,their levels have the guiding significance in evaluation of severity of liver fi-brosis in the patients with hepatitis B .

Esophageal reconstruction is of great importance in the practice of esophagectomy,and esophagogastric anastomosis represents the most essential and key technical aspect of the operation,which largely determined patients' shortterm outcomes.A successful esophageal anastomosis should be no occurrences of postoperative early-stage anastomotic bleeding and leakage and later-stage anastomotic stenosis.The circular stapler,linear cut stapler and hand-sewn anastomosis are the most common anastomotic methods.Hand-sewn anastomosis is the most traditional and classical.Circular stapler has gained significant popularity for its simplicity and convenience.Linear cut stapler used for side-to-side anastomosis has the potential to reduce the risk of postoperative anastomotic stenosis via expanding inner diameter of anastomosis.Every anastomotic method has its advantages and disadvantages,and it cannot completely avoid occurrence of postoperative anastomotic complications.To have a better outcome,both surgeon's experiences and patient's individual conditions should be taken into consideration for the choice of anastomotic technique.

Immune checkpoint inhibitors have become an important alternative for advanced non-small cell lung cancer (NSCLC) patients to surgery, chemotherapy, radiotherapy and targeted therapy. Monoclonal antibodies directed against immune checkpoint have shown better results in the application of first- or second-line treatment of NSCLC and for both squamous and non-squamous cell carcinoma patients, especially for those with positive PD-L1 tumor cells. Some comments will be made in present paper about the efficacy, biomarker, combined therapy and the resistant mechanism of immune checkpoint inhibitors.

Objective To investigate the clinical efficacy of imipenem and cilastatin sodium on the clinical efficacy of elderly patients with severe bacterial infection, and to observe the clearance rate to different floras.MethodsA total of 206 elderly patients with severe bacterial infection as the research object in our hospital outpatient treatment, were divided into control group and observation group, the patients were collected with sputum, blood and urine samples sent for bacterial culture.All patients were given positive treatment and nursing care, the observation group was given imipenem and cilastatin sodium treatment,the control group was given cefotaxime sodium treatment.The clinical efficacy, bacterial clearance and adverse reactions of the two groups were recorded and compared.ResultsThe total efficiency rate was 91.26% in the observation group, and 79.61% in the control group.The number of effective cases was significantly higher in the observation group than in the control group (P<0.05), the number of ineffective cases was significantly lower than that of the control group (P<0.05);The bacterial clearance rate was 85.71% in the observation group, and 43.33% in the control group, the clearance rate of Bauman Acinetobacter, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus was significantly higher in the observation group than in the control group (P<0.05).Through the detection of adverse reactions showed that the observation group and the control group after treatment, few patients mild symptoms of nausea and vomiting and itching rash, on the occurrence of adverse reactions of the two groups of patients were compared, the difference was not statistically significant.ConclusionFor elderly patients with severe bacterial infection with imipenem and cilastatin sodium for treatment, the effective rate is high and can timely remove a variety of pathogenic bacteria, and rare adverse reactions, high safety, worthy of clinical application.

OBJECTIVE: To establish a new method for measuring the content of benzalkonium bromide in disinfectant so- lution METHODS: The sodium nitrite was removed from disinfectant solution by reaction between sodium nitrite and urea to form N2 and CO2 and then benzalkonium bromide in the solution was directly determinated by UV-spectrophotometry with no need of separation RESULTS:There was no significant difference between this method and the method in pharmacopeia CON CLUSION:The method is simple, rapid and accurate and can be used to measure benzalkonium bromide in the solution.

BACKGROUND: Kyphosis in ankylosing spondylitis is sagittal or coronal imbalance, but there is a lack of study on its orthopedic biomechanics, and biomechanics is of great significance for the reconstruction of spinal stability after orthopedic surgery.OBJECTIVE: To establish a three-dimensional (3D) finite element model of kyphosis in ankylosing spondylitis treated by osteotomy on software, and to analyze its biomechanical properties, thus providing theoretical basis for clinical practice.METHODS: A 3D finite element model of kyphosis in ankylosing spondylitis was established based on CT data, and the predetermined angle of the osteotomy at L2 was measured. Afterwards, vertebral column decancellation and vertebral column resection were stimulated, and then the biomechanical parameters were analyzed. RESULTS AND CONCLUSION: (1) The 3D finite element models of kyphosis in ankylosing spondylitis treated by vertebral column decancellation or vertebral column resection at L3 were established successfully. (2) The stress on the screw and contact at each segment in the vertebral column decancellation group was significantly higher than that in the vertebral column resection group except for S1. (3) To conclude, both two methods can reconstruct the sagittal balance,but vertebral column decancellation exhibits significantly higher stress on the screw. Indeed, the incidence of internal fixation failure and complications in vertebral column decancellation is higher than that in vertebral column resection at the same segment and angle.
