OBJECTIVE:To provide reference and evidence for rational use of clinical nutrition. METHODS:The types of en-teral and parenteral nutrition and the cost of prescription were analyzed statistically in 17 third grade class A general hospitals,3 third grade class A special hospitals and 14 secondary general hospitals from Shanghai area during 2011 to 2013. RESULTS:Nutri-tion preparations were mainly used by hospitalized patients. Total cost of nutrition preparations in outpatient and emergency depart-ment respectively occupied 8.14%,8.77% and 8.89% of total cost of nutrition preparations in the hospital during 2011-2013. The parenteral nutrition was the main form of nutritional support. There were only three kinds of enteral nutrition in top ten nutrition preparations in the list of prescription cost. Although seven out of ten kinds of nutrition preparations were given enterally which was the main mode for outpatients and emergency patients,the cost of prescriptions of parenteral nutrition increased faster compared to enteral nutrition,especially alanyl-glutamine. CONCLUSIONS:Parenteral nutrition is the main mode of nutrition support,especial-ly for inpatients;great attention should be paid to the increase of the cost of prescriptions about parenteral nutrition in outpatients and emergency patients.

Objective:Study on the feature of thrombin-antithrombin complex (TAT) during traumatic brain injury and the predicting performance with adverse clinical outcomes.Methods:From January 2018 to December 2019, 147 patients with traumatic brain injury(TBI) were enrolled, including 112 males and 35 females, aged 36 (26-48) years old. The plasma levels of TAT were detected on the 0th, 1st, 3rd and 7th day after TBI attack. Kruskal-Wallis H test was used for comparison among multiple groups; Mann-Whitney U test was used for data comparison between the two groups; continuous comparison of patient data in the same group using Friedman rank test; the diagnostic performance of TAT with adverse event risk predicting was evaluated by ROC analysis; Kaplan-Meier curve was used to analyze the survival curve; the risk ratio (HR) was obtained by Cox proportional hazard regression model.Results:Among the patients groups with mild, moderate and severe phenotype, the TAT levels were gradually decreased on the 0th, 1st, 3rd and 7th day after TBI attack(χ 2 values were 95.612, 133.555, and 132.453, respectively, all P values<0.001). The TAT levels on the 0th, 1st, 3rd and 7th day in the adverse event group were higher than in the group of patients with stable condition ( U values were 959.0, 321.0, 36.0 and 1.0 respectively, all P values<0.001). In the stable condition group, the TAT levels on the 0th and 1st day in the severe group were higher than in the mild group ( U values were 0 and 1.0 respectively, both P values<0.001), while there was no statistically significant difference of TAT levels between the 3rd and 7th day in the severe group ( U values were 342.5 and 272.5, P values were 0.486 and 0.065 respectively). The TAT levels of the moderate group on 0th and 1st day were higher than those of the mild group ( U values were 0 and 280.0, respectively, both P<0.001), while there was no significant difference between the TAT levels on the 3rd and 7th day ( U values were 628.0 and 647.0, P values were 0.826 and 0.996, respectively). ROC curves analysis showed that when the TAT diagnostic thresholds were 68.75 ng/ml, 29.05 ng/ml, 17.25 ng/ml and 13.85 ng/ml on the 0th, 1st, 3rd and 7th day, the diagnostic sensitivities of predicting adverse events were 86.8%, 94.3%, 100% and 100%; while the diagnostic specificities were 71.3%, 78.7%, 91.5% and 96.8%, respectively. Survival analysis showed that the cumulative probability of adverse outcomes was significantly higher in patients above the critical value. Cox analysis showed that the HR on the 0th, 1st, 3rd and 7th day to predict adverse clinical outcomes by TAT levels were 1.818, 2.257, 3.526 and 4.813, respectively ( P value<0.001). Conclusion:There was strong relationship between the plasma TAT level and the severity of the patient′s condition, and persistent increasing with TAT level could reflect the risk of adverse events, which could be used as an effective index to comprehensively predicting the development tendency of the TBI patient′s condition.

Objective To investigate the efficacy and safety of modified endoscopic submucosal dissection (ESD) and rubber band ligation assisted endoscopic dissection for treatment of small gastric submucosal tumors (SMT) originating from the muscularis propria layer. Methods A total of ninety-two patients diagnosed as gastric SMT (6 mm≤diameter≤13 mm) originating from the muscularis propria layer by EUS in our hospital were enrolled in this study. With intravenous anesthesia and tracheal intubation in all patients, modified ESD was performed firstly to stripe the small tumors. After being exposed to a certain extent, the tumors were ligated by rubber band and snared for endoscopic dissection. The situation of bleeding, perforation in both intraoperative and postoperative, the integrity and size of the resected specimens were observed and recorded. The resected specimens were identified with histopathological detection and immunohistochemistry assay. At the 6-month and 12-month after the operation, all patients were reviewed by gastroscopy and EUS in our hospital. Results All the 92 tumors were resected completely and successfully. The mean operating time was (19.2±2.3) min and the mean blood loss in operation was (2.6±0.5) mL. Perforation after resection occurred in 3 cases, which were closed with metal hemostatic clips and nylon ropes. No delayed bleeding and perforation occurred in one week after the operation. The tumor sizes ranged from 6 mm × 5 mm to 13 mm × 12 mm. Seventy-three gastric stromal tumors (risk classification:all were very low risk), 18 gastric leiomyomas and 1 gastric neurofibroma were identified. There were no residue or recurrence in all cases during the 12-month follow-up period. Conclusion The modified ESD and rubber band ligation assisted endoscopic dissection are effective and safe for treatment of small gastric submucosal tumors originating from the muscularis propria layer. The tumors are resected completely and successfully, showing certain significance to assess the nature, degree of malignancy of the tumor and prognosis of the patients.

Objective To develop a gene chip for the detection of common pathogens causing urogenital sexually transmitted infections. Methods The target pathogens were divided into three groups: viruses, bacteria, and lower eukaryotes. Three pairs of universal primers were designed and applied to amplify the target genes of these different pathogens in one PCR reaction system. The gene chips were then prepared via immobilization of the specific probes onto specially treated glass slides. Finally, the labeled amplicons were hybridized with the gene chips, scanned and analyzed using computer software. Results Amplicons were detected by agarose gel electrophoresis. The fluorescence signals for specific pathogens could be recognized in the gene chips, and were identical with the positions of the specific probes. Conclusions Gene chip is a specific, sensitive and rapid method for simultaneous detection of multiple sexually transmitted infections.

Background:
Gout is the most prevalent form of inflammatory arthritis in the world. Total hip arthroplasty (THA) has emerged as a widely sought-after and highly effective surgical procedure for advanced hip diseases. However, there is a lack of research on the impact of gout on primary THA outcomes in large cohorts. This study aimed to address this gap by primarily investigating complications following THA in patients with or without gout.
Methods:
Patients with records of gout in the 2 years leading up to their primary THA and who also have at least 2 years of follow-up were identified using a national insurance database and compared to a 5:1 matched control. A total of 32,466 patients with gout and 161,514 patients without gout undergoing THA were identified. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to 2 years. In addition, 90-day emergency department (ED) visits and inpatient readmission were also documented.
Results:
Patients with gout demonstrated higher rates of medical complications including deep vein thrombosis, transfusion, acute kidney injury, and urinary tract infection than non-gout patients (p < 0.001). Gout patients also showed higher rates of pulmonary embolism (p = 0.017). Increased incidences of surgical complications were identified in gout patients, specifically wound complications and periprosthetic joint infection (p < 0.001). There was an increased risk of revision for gout patients up to 90 days (p = 0.003), 1 year (p = 0.027), and 2 years (p = 0.039). There was also an increased risk of dislocation for gout patients up to 90 days (p = 0.022) and 1 year (p = 0.047), but not at 2 years. No significant difference was observed in aseptic loosening or periprosthetic fracture. Additionally, gout patients also demonstrated a higher likelihood of 90-day ED visits and readmission (p < 0.001).
Conclusions
Primary THA in gout patients is associated with increased risks of multiple medical and surgical complications. Our findings provide insights into the planning and expectation of THA for patients with gout. These insights have the potential to benefit the decision-making process for gout patients considering THA.

Background:
While it is known that patients with end-stage renal disease (ESRD) are at an increased risk of complications following total hip arthroplasty (THA), there is a gap in the literature in comparing patients with ESRD to patients who undergo renal transplant (RT) before or after THA. This study is to address this gap by analyzing outcomes of THA in ESRD patients, RT patients, and RT candidates.
Methods:
Using the PearlDiver Mariner database, ESRD patients, RT patients, and RT candidates undergoing primary THA were identified and compared. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to 2 years. Ninety-day emergency department (ED) visits and inpatient readmission were also documented.
Results:
A total of 7,868 patients were included: 5,092 had ESRD, 2,520 had RT before THA, and 256 were candidates for RT. Compared to patients with ESRD, RT patients demonstrated lower rates of medical complications such as pneumonia (3.61% vs. 5.99%, p = 0.039) and transfusion (4.60% vs. 7.66%, p < 0.001). Additionally, RT patients displayed decreased rates of surgical complications, including wound complications (2.70% vs. 4.22%, p = 0.001), periprosthetic joint infection (PJI) at 1 year (2.30% vs. 4.81%, p < 0.001) and 2 years (2.58% vs. 5.42%, p < 0.001), and aseptic loosening at 2 years (0.79% vs. 1.43%, p = 0.006). Similarly, when compared to RT candidates, RT patients demonstrated a lower incidence of postoperative complications, including 1-year PJI (2.30% vs. 5.08%, p = 0.013), 2-year PJI (2.58% vs. 5.08%, p = 0.028), 1-year aseptic loosening (0.56% vs. 2.73%, p < 0.001), and 2-year aseptic loosening (0.79% vs. 2.73%, p = 0.005). RT patients also had lower rates of ED visits and hospital readmissions.
Conclusions
Compared to ESRD patients and RT candidates, patients with RT have a significantly lower likelihood of medical complications, PJI, aseptic hardware loosening, ED visits, and hospital readmission. Patients with ESRD on the RT waiting list should delay THA until after RT surgery. For those not eligible for RT, it is vital to take extra precautions to reduce the risk of complications.

OBJECTIVE:To construct integrated medication decision-making system,and to provide reference for safe,effec-tive,economical and reasonable drug use in clinic. METHODS:The construction of integrated medication decision-making system was introduced in our hospital. RESULTS&CONCLUSIONS:The integrated medication decision-making system included three as-pects as real-time intervention in advance,interactive review in the matter,afterward comment and analysis,as 3 steps before and after the implementation of inpatient medical order and outpatient prescription. The real-time intervention in advance was mainly to control the rationality of medical orders or prescriptions from their source,thus requiring the timely treatment. The interactive re-view in the matter required that pharmacists judged the medical order or prescription and made a decision of refusing prescribing within the fixed time. To make a decision accurately,the clinical information should be highly structured and correlated with drug signs. Afterward comment and analysis required that pharmacists evaluated the medical order or prescription regularly after the im-plementation. The three were not only different,but also coordinated,and they were an organic unity,especially interactive review in the matter needed to be coordinated with the other two processes. After the implementation of integrated medication decision-mak-ing system,the proportion of irrational medical orders or prescriptions in our hospital decreased from 6.07% in the first half of 2016 to 2.56% at corresponding period of 2017. Drug dose errors and incompatibility were greatly reduced,and medication against contraindications was more likely to be found in the review and analysis. The system can improve the efficiency of prescription re-view,improve rational drug use,and effectively ensure the safety,effectiveness,economy and rationality of clinical drug use.

Objective To explore the current training programs for preventive medicine undergrad-uates in China's colleges and universities, so as to provide more clues for further optimizing the training program. Methods Twelve colleges and universities were selected in accordance with the stratification of 985, 211 and general colleges and universities and their training programs for preventive medicine under-graduates were collected in February, 2016. By comparing with the requirements of "The directory and introduction of undergraduate courses in colleges and universities (2012)" and the spirit of the second round of "undergraduate teaching evaluation of higher education institutions", training programs were described; t test and multivariate analysis of variance were used to compare differences among different levels of colleges and universities;SPSS 21.0 was used for statistical processing. Results In some colleges and universities, training programs were still not concrete and the setting of three common core courses (Health Education, Health Service Management and Women's Health Science) did not meet the require-ments of the new directory of 2012. All selected colleges and universities had established their standards of the minimum curricular credits ( including course system and internship practical training ) which were(245.33±27.01) credits. In course system, the required course and the elective course were (176.25±18.46) credits, (26.62±12.68) credits, respectively. The percentage of preventive medicine in required courses was relatively lower, only (21.99 ±3.50)%. In internship and practical training, the clinical practice and the specialty practice were (20.00 ±5.13) weeks, (27.33 ±7.78) weeks, taking (16.46 ±7.75) credits, (23.50 ± 9.86) credits, respectively. No differences were found in courses setting, credits distribution among 985, 211 and general universities and colleges, all P>0.05. Conclusion There still exist problems: training pro-grams are not concrete and the training system cannot fully reflect training objectives in some colleges and universities, needing to be further standardized and improved.

Objective:Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube.Methods:3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length.Results:In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice.Conclusion:MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.
