OBJECTIVE To evaluate the standard of non-invasive diagnosis of Down′s syndrome between the different PCR machines. METHODS Two kinds of PCR machines were used respectively to amplify the homologous genes-the human liver-like phosphofructokinase gene (PFKL) and the human muscle-like phosphofructokinase gene (PFKM). RESULTS The best annealing temperature of the two PCR machines were 64 ℃ and 60 ℃,and only in this reaction conditions PFKL′s and PFKM′s electrophoresis strips had the same optical density value. CONCLUSIONS This approach has proven that the conditions of amplified the PFKL and PFKM are different between the two kinds of PCR machines.

Objective To investigate the concentration of Golgi glycoprotein 73(GP73) in ascites, then study the value of GP73 and alpha fetal protein(AFP)in the differential diagnosis of ascites.Methods Totally 96 malignant ascites specimens , 35 benign ascites specimens and their paired serum specimens were collected in the Tumor Hospital Affiliated to Xinjiang Medical University from November 2012 to November 2013.GP73 in serum and ascites were detected by ELISA and AFP in ascites was measured by electrochemical luminescence.The application values of GP 73 and AFP were evaluated through ROC curve.Results In benign ascites group , the difference of GP73 between the ascites ( 16.06 ±9.53 ) ng/ml and the serum (13.69 ±8.87) ng/ml was statistically significant (t=5.026,P<0.001), which showed a good linear correlation (r=0.966,P<0.001).In malignant ascites group, the difference between the ascites (28.37 ±12.02) ng/ml and the serum (16.06 ±9.53) ng/ml was statistically significant (t=10.641,P<0.001), and also showed a good linear correlation (r=0.933,P<0.001).The cutoff values of GP73, AFP and GP73*AFP (GP73 multiplied AFP) for diagnosing the malignant ascites were 17.1 ng/ml, 13.1 ng/ml and 321.The area under ROC curve ( AUC) were 0.795, 0.753 and 0.902 respectively.The AUC of GP73*AFP is the largest.The sensitivity of three index diagnosing the ascites , were 89.6%( 86/96 ) , 88.5%(85/96) and 86.4%(83/96); and the specificity were 60.0%(21/35), 54.2%(19/35) and 85.7%( 30/35 ) respectively.Conclusions Detection of GP73 in ascites specimens has clinical value , GP73*AFP was the best indicators for differential diagnosis of benign and malignant ascites compared to GP73 and AFP.

A UPLC-ESI-MS/MS method was used to determinate the main active fractions gallic acid, protocatechuic acid, myricetrin, hyperoside and quercitrin in Polygonum capitatum extracts by in situ intestinal perfusion models; the absorption rate constants and cumulative penetration rate of absorption were calculated. The effect of different drug concentrations, different intestine segments, bile and P-gp inhibitors on the absorption mechanism of Gallic acid and other compositions in P. capitatum extracts. The experimental results showed that gallic acid, protocatechuic acid, myricetrin and quercitrin were observed saturated at high concentration (P < 0.05). Bile had significant inhibition effect on protocatechuic acid absorption and had promotion effect on myricetrin and hyperoside absorption (P < 0.05). P-gp inhibitor verapamil could significantly enhance the absorption of Protocatechuic acid (P < 0.05). The overall trend for absorption of various compositions was that small intestine > colon. This indicated that the absorption mechanism of P. capitatum extracts in rat intestine was in line with fist-order kinetics characteristics. The composition could be absorbed in all of the different intestinal segments, and the absorption was mainly concentrated in small intestine. The protocatechuic acid may be the substrate of P-gp.

Objective To develop a blood gas,acid-base imbalance analysis computer software to diagnose systematically,rapidly,accurately and automatically determine acid-base imbalance type,and evaluate the clinical application. Methods Using VBA programming language,a computer aided diagnostic software for the judgment of acid-base balance was developed. The clinical data of 220 patients admitted to the Second Affiliated Hospital of Guangzhou Medical University were retrospectively analyzed. The arterial blood gas〔pH value,HCO3-,arterial partial pressure of carbon dioxide(PaCO2)〕and electrolytes included data(Na+and Cl-)were collected. Data were entered into the software for acid-base imbalances judgment. At the same time the data generation was calculated manually by H-H compensation formula for determining the type of acid-base imbalance. The consistency of judgment results from software and manual calculation was evaluated,and the judgment time of two methods was compared. Results The clinical diagnosis of the types of acid-base imbalance for the 220 patients:65 cases were normal,90 cases with simple type,mixed type in 41 cases,and triplex type in 24 cases. The accuracy of the judgment results of the normal and triplex types from computer software compared with which were calculated manually was 100%,the accuracy of the simple type judgment was 98.9% and 78.0% for the mixed type,and the total accuracy was 95.5%. The Kappa value of judgment result from software and manual judgment was 0.935,P=0.000. It was demonstrated that the consistency was very good. The time for software to determine acid-base imbalances was significantly shorter than the manual judgment(seconds:18.14±3.80 vs. 43.79±23.86,t=7.466,P=0.000),so the method of software was much faster than the manual method. Conclusion Software judgment can replace manual judgment with the characteristics of rapid,accurate and convenient,can improve work efficiency and quality of clinical doctors and has great clinical application promotion value.

Objective:To explore the status of depression symptoms and related factors of depressive symptoms in middle-aged and elderly disabled people in China and provide references on the preventive cares of depression.Methods:Research data were obtained from the 2018 follow-up data of China Health and Retirement Longitudinal Study(CHARLS).Disabled people were selected as the research object. The scores of center for epidemiological studies depression scale(CES-D) were used to evaluate depressive symptoms. Fourteen variables derived from the 3 dimensions of demographic characteristics, health status, and health related behaviors were utilized in this study.SAS 9.4 were used for descriptive analysis, univariate analysis and Logistic regression analysis.Results:A total of 1 708 middle-aged and elderly disabled people were included, among whom 932(54.5%)were diagnosed with depressive symptoms, and the score of CES-D was (11.45±7.19).Self-rated poor health, self-rated poor memory, life dissatisfaction, physical pain were the risk factors of depressive symptoms ( OR=1.87, 4.22, 1.83, 5.30, 1.75). Male, educational level (middle-high school, high school or above), sleeping duration (6-9 h) were the protective factors of depressive symptoms( OR=0.74, 0.72, 0.10, 0.56). Conclusion:Middle-aged and elderly disabled people in China have a high detection rate of depressive symptoms. Female, lower education background, inadequate amount of sleep, self-rated unsatisfactory healthy, self-rated poor memory, dissatisfaction towards life and suffering from physical pain may be more likely to have depressive symptoms in middle-aged and elderly people with disabilities.

OBJECTIVE: to investigate the origin characters of snore in simple snorers and provide the basis for its treatment. METHOD: Thirty-two simple snorers diagnosed by polysomnography were induced to sleep by propofol and dexmedetomidine, then we observed the vibration sites, pattern and concomitant collapse of soft tissue in pharyngeal cavity by nasendoscopy. RESULT: Thirteen cases showed palatal fluttering only, and 1 case showed vibration of epiglottis only. Six cases showed palatal fluttering with vibration of epiglottis, and 2 cases showed palatal fluttering with vibration of epiglottis and tongue base. Five cases showed palatal fluttering with vibration of pharyngeal lateral wall, and 5 cases showed palatal fluttering with vibration of lateral wall, epiglottis and tongue base together. Palate and pharyngeal lateral wall vibrated strongly and always collapsed with vibrating, but epiglottis and tongue base usually vibrated slightly and seldom collapsed. CONCLUSION The palatal fluttering is the main source of snoring sounds for most simple snorers, then followed by vibration of palatal and pharyngeal lateral wall together. The site of collapse in pharyngeal cavity is consistent with the main site of vibration.
