Objective To stady the diagnosis and management of traumatic chylous ascites.Methods Retrospective analysis was conducted on the clinical dada of 11 cases of traumatic chylous ascites resulting from various causes.ResultsThere were 5 cases of open abdominal injury,2 cases of closed abdominal injury and 4 cases of operative injury.Nine cases were treated with operation.According to the location and extent of injury,patients were respectively managed by operation of direct repair or ligation.Two cases had non-surgical treatment.All of the11 patients were cured and had satisfactory result at 0.5~3 years of follow-up.ConclusionsFor traumatic chylous ascites,if the injurg occurrence on cisterna chili,the best treatmeat is primary repair;if injury occarrence on the small intestinal trunks or lumbar trunk,which can be treated with ligation;while blunt injury and cases found after operation are mainly treated conservatively.
4.Peptide retention prediction algorithm and its application in proteomics
Journal of China Pharmaceutical University 2021;52(4):422-430
Most of the proteomics analysis methods based on tandem mass spectrometry rely on the matching scoring of actual spectrum and theoretical spectrum, the interference of a large number of co-eluting peptides could cause error in the identification and quantification of peptides and proteins. Peptide retention time prediction, as a auxiliary and verification index of the peptide, can transition the chromatographic behavior into stable independent time attributes, and improve the accuracy of the peptide identification. Prediction of peptide chromatographic retention in complex systems is also of great significance for optimizing proteomics determination conditions and improving the detection rate and repeatability of mass spectrometry data in data-independent acquisition. This review focused on the chromatographic retention prediction method of unmodified peptides and modified peptides, summarizes the content, characteristics and limitations of four types of peptide retention time prediction methods based on standardized indexes, peptide molecular models, amino acid residue parameters, and machine learning, as well as their applications in proteomics, with a prospect of their future.

Facilitate patient visits, rational use of equipment, improve work efficiency and improve the treatment environment.
6.Effects of different administration modes of hydrocortisone sodium succinate on patients with severe sepsis secondary shock
Chongqing Medicine 2017;46(24):3354-3355,3369
Objective To study the influence of hydrocortisone sodium succinct by intravenous infusion or continuous intravenous micro pumping on the vital signs,shock duration,blood glucose and mortality in the patients with severe sepsis secondary shock.Methods Ninety patients with septic shock treated in our hospital from June 2014 to September 2016 were selected and divided into the control group and observasion group by using the random number table method,45 cases in each group.The control group was given hydrocortisone sodium succinct 200mg/d by slow intravenous drip for 2h,while the observasion group was given hydrocortisone sodium succinct 8.33mg/h by continuous intravenous micro pumping.The two groups were treated for continuous 5 d.The blood glucose,hemodynamics and prognosis were compared between the two groups.Results In the observasion group,the blood glucose indicators such as the time window of high blood glucose,LAGE,MBG and CV levels were lower than those in the control group,the difference had statistical significance (P<0.05).The hemodynamic indicators such as HR,CVP and MAP between the two groups before treatment and at 6,24 h and 5 d after treatment had no statistical difference between the two groups (P>0.05).The shock duration,ICU stay length,total hospital stay and 28 d mortality in the observasion group were lower than those in the control group,but the difference between the two groups had no statistical significance (P>0.05).Conclusion Continuous intravenous micro pumping of hydrocortisone sodium succinct can stabilize blood glucose fluctuation range in the patients with septic shock,but the hemodynamic indexes and prognosis have no obvious improvement.
7.Effects of 70 pearl flavor pill associating with acupuncture on nerve function in acute cerebral infarction patients
Chinese Journal of Biochemical Pharmaceutics 2017;37(7):159-161
Objective To analyse the effect of 70 pearl flavor pill associating with acupuncture on nerve function in acute cerebral infarction patients.Methods A total of 128 patients with acute cerebral infarction were enrolled in this study in our hospital from January 2015 to June 2016 and randomly divided into two group.Two groups were treated with routine treatment,the observation group was treated another with 70 pearl flavor pill combined with acupuncture program.Results The total effective of observation group was 92.19%,higher than that of control group 75.00%(P<0.05).After treatment,NIHSS score,FMA motor function score,Serum S-100βprotein,hs-CRP level of observation group were better than that of control group (P<0.05).Conclusion 70 pearl flavor pill associating with acupuncture on the basis of routine treatment can improve hemorheology,reduce inflammation and improve the therapeutic effect and it has no obvious side effects.

Objective To perform an acceptance test for the IMRT system with independent collimator. Methods An ion chamber dosimeter were used to measure the startup characteristics of the accelerator and the absolute dose at isocenter and given characteristic points for three clinical cases ( a lower nasopharyngeal carcinoma, a lung cancer and a cervical cancer). The characteristic points represented the organs at risk or the target. A Mapeheck2 was used to measure dose maps of basic test fields and the treatment fields for the clinical cases. The basic test fields were as follows: 1 ). Symmetric fields in size of 2 cm ×2 cm, 5 cm ×5 cm, 10 cm× 10 cm, 20 cm ×20 cm, 2 cm × 10 cm, 10 cm ×2 cm, 5 cm ×20 cm and 20 cm ×5 cm;2). Asymmetric fields in size of 2 cm ×2 cm (x1 =4 cm, y1 = 10 cm;x2 = -2 cm, y2 = -8cm) and 5 cm ×5 cm (x1 = -2 cm, y1 = -5 cm;x2 =7 cm, y2 = 10 cm) ;3) A 20 cm ×20 cm composite field composed of five 20 cm× 4 cm narrow bar fields side by side. Gamma Index was used to compare calculated and corresponding measured dose distributions. When the criterion was 3% dose difference or 3 mm distance-to-agreement, the pass rate was required to be more than 90%. Results The accuracy of machine output was better than 2% when machine monitor units increased to 4. Among all basic test fields and all the treatment fields of three clinical cases, the maximal absolute dose error was -3.67%, and only the composite test field and two treatment fields of the lower nasopharyngeal carcinoma case had a pass rate slightly less than 90%, which were 83.6%, 88. 3% and 89. 7% ,respectively. For the three clinical cases the treatment delivery times were 15, 14, and 27 minutes, respectively. Conclusions The overall commissioning results are acceptable, and the system can be used in clinic.
