Objective To investigate the problems during using, standard and quality management of the POCT glucose meters in hospital, to analyze the solutions, and to provide reference data for improving the test level of POCT in hospital.Methods The amount, brand and application of portable glucose meters in the hospital were obtained by 3 rounds of surveillance from May to July in 2013.All of those glucose meters were taken part in external quality assessment of Clinical Laboratory Center of National Health and Family Planning Commission.The test results of those glucose meters were compared with that of automatic biochemical analyzer, the comparison results were then analyzed.Results The POCT glucose meters possessed 5 brands in our hospital, and the amount and type of glucose meters in some clinical departments were often changed.When 4 brands which were detected as quality control samples by ministry of health, the accuracy of detection results of 3 concentration of brand Ⅲ were substandard, the CV% of two levels were 11.9%and 10.1%respectively, the remaining 3 brands were in line with the requirements.The qualified percentages of 3 times of comparison were 85.0%, 92.0%and 97.4%.Conclusions The hospital should select the brand of portable glucose meters reasonably, correct use of glucose meters, and it is very necessary to build indoor and interstitial quality evaluation system, at the same time, suggesting the hospital to establish the POCT quality management team, to carry out the instrument comparison periodically, so to guarantee the accurate, reliable results of POCT in hospital.

Based on the chemical structures of magnolol and honokiol,a series of small molecular derivatives were designed for the treatment of Alzheimer's disease.Through the Discovery Studio,five compounds (6a-6e) exhibited the inhibitory activity against Aβ and Tau proteins in all of the designed compounds.Then the five compounds are chemically synthesized and their biological activities were tested by thioflavin T.The result showed that compound 6a had inhibitory effect on the aggregation of two kinds of target proteins at the concentration of 100 μmol/L,which deserves further research.

Objective:
To explore the clinical effect of a novel artery first and uncinate process first approach for laparoscopic pancreaticoduodenectomy(LPD), emphasizing the left lateral and posterior dissection of uncinate process (UP) via Treitz ligament approach.
Methods:
From April to November 2016, 18 patients received LPD with a novel approach in Pancreas Center of the First Affiliated Hospital with Nanjing Medical University. All patients were diagnosed as pancreatic head or peri-ampulla tumor, without major vessel invasion nor distant metastasis. For resection, routine caudal view was used in the first step, to dissect the anterior medial border between uncinate process and superior mesenteric vein(SMV). Lymphatic tissues were completely dissected form anterior surface of hepatoduodenal ligament. In the second step, left lateral view with camera from left para-umbilical trocar was used, Treitz ligament was incised, SMA root was exposed. After anticlockwise rotation and retraction of mesentery, the anatomic relationship between SMA trunk, inferior pancreaticoduodenal artery(IPDA), jejunal branch of SMV, and distal part of UP, could be perfectly exposed from left lateral view. SMA was dissected from its root until the position above the uncinate process and duodenum, IPDA was transected, distal part of UP was freed from SMA. In the third step, right lateral view and caudal view were alternatively used; proximal UP mesentery was completely dissected out from SMA root, CA root and posterior surface of hepatoduodenal ligament. Pancreaticoduodenectomy was completed in the forth step after transection of pancreatic neck and common hepatic duct.
Results:
The SMA root and distal UP were successfully dissected out via Treitz ligament approach in all 18 patients, among them, distal UP was completely excised in 8 patients from left view. Postoperative pathology showed R0 resection rate in 69%. Postoperative complication included intra-abdominal hemorrhage in 1 patient, pancreatic fistula in 7 patients(6 cases with grade A and 1 case with grade B), delayed gastric emptying in 4 patients (2 cases with grade A, 2 cases with grade B). Average postoperative hospital stay was (15.5±6.8)days.
Conclusion
The novel artery first and uncinate process first approach through Treitz ligament could help surgeons to completely dissect the full length of meso-pancreas along celiac axis-SMA axis in LPD.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.
