Objective To investigate the development of the digital wireless network billing system of oxygen flow in clinical application. Methods By random 220 cases of patients who need to absorb oxygen were divided into the observation group(108 cases)and the control group(112 cases), the observation group used the digital wireless network billing system of oxygen flow, and the control group adopted the traditional buoy type oxygen gauge instrument. The following items were compared between the two groups: dispute rates between nurses and patients for different amount of absorbed oxygen, the average time cost for nurses in measuring the duration of oxygen absorbing, total income per barrel for recycling oxygen. Results For the dispute rates between nurses and patients for different amount of absorbed oxygen were 0.93% in the observation group, and 75.89% in the control group. The average time cost for nurses in measuring the duration of oxygen absorbing was 2.03 minutes for the observation group, and 12.54 minutes for the control group; total income per barrel for recycling oxygen was 42.68 yuan per barrel of the observation group, and 28.23 yuan in the control group. The statistical analysis between the two groups was supported by 95% confidential level. Conclusions Using the digital wireless network billing system of oxygen flow in clinical can reduce the dispute rates between the nurses and patients, improve patients' satisfaction degree, reduce the total time cost for nurses in measuring the duration of oxygen absorbing, raise efficiency, build a clear scientific charge system of oxygen flow, and restore economic loss.

Objective To explore the timing of surgical intervention for severe acute pancreatitis (SAP). Meth-ods One hundred and fifty-seven cases with SAP treated in our hospital from March, 1998 to December, 2007 were analyzed retrospectively. Influence of surgical intervention and conservative treatment on curative rate were e-valuated in pancreatic necrotic area and with or without infected pancreatic necrosis. Results The overall curative rate of surgical treatment and conservative treatment was 80.4%, 87.1% respectively; the two methods had no sta-tistical difference. Conservative treatment was better than surgical treatment in patients with lesa than 30% necrotic area and surgical treatment was better than conservative treatment in patients with more than 50% necrotic area. But the two methods had no statistical difference in 30% ～ 50% necrotic area. Conservative management was better than surgical management in sterile pancreatic necrosis, but surgical management was better than conservative manage-ment in pancreatic necrosis with infection or suspection of infection. Conclusion Surgical intervention treatment plays an important role in SAP patients, we should combine pancreatic necrotic area and with or without infection to choose the timing of surgical intervention for severe acute pancreatitis.

Objective The widely use of ultrasound elastography has increased the detection rate of breast cancer.It has great advantage of differential diagnosis of breast tumor.Our study is to evaluate and compare the value of the quantitative ultrasound elastography parameters of AR ( area ratio) , ESR ( entire strain ratio) , LSR ( locolized strain ratio) , EFLR( entire fat to lesion ratio) and LFLR( locolized fat to lesion ratio) in the differential diagnosis of breast tumor. Methods 110 patients with 113 breast tumors were collected from Nanjing General Hospital of Nanjing Military Region between January 2015 and January 2016 who underwent breast exami-nation.The tumors were divided into two groups according to patholo-gy which acts as gold standard:benign group with 59 lesions and ma-lignant group with 54 lesions.Participants underwent quantitative ul-trasound elastography parameters examination.AR、ESR、LSR、EFLR、LFLR were compared between benign group and malignant group and ROC curve was drawn.Conventional ultrasound and ultrasound elastography parameter are combined to differentiate the benign or malignant lesion.Calculate the various parameters on the accuracy、susceptibility、specificity、positive likelihood ratio、negative likeli-hood ratio of the diagnosis of benign and malignant lesions, and determine the quantitative parameter with the highest accuracy. Results The mean value of AR、ESR、LSR、EFLR and LFLR of malignant lesions were all significantly greater than that of benign le-sions (P=0.000).Compared with the conventional ultrasound, AR、ESR、LSR、EFLR and LFLR have higher AUC in the differentia-tion of benign and malignant breast lesions;AUC of AR and ESR are higher than conventional ultrasound、LSR、EFLR and LFLR( P<0.000).Compared with conventional ultrasound(1.523) alone, conventional ultrasound combined separately with AR、ESR、EFLR and LFLR have higher positive likelihood ratio(11.581、8.272、3.482、2.458、2.100) in the differentiation of benign and malignant breast lesions, so as accuracy、susceptibility、specificity(P<0.000).The AUC of conventional ultrasound combined separately with AR and ESR[0.940(0.890~0.990)、0.941(0.891~0.990)] were higher than conventional ultrasound and conventional ultrasound com-bined separately with LSR、EFLR、LFLR[0.669(0.669~0.768)、0.837(0.759~0.915)、0.763(0.673~0.852)、0.787(0.701~0.874)],so as accuracy、susceptibility、specificity and positive likelihood ratio(P<0.000). Conclusion Quantitative ultrasound elastography may be helpful in differentiation of benign and malignant breast lesions, especially combining conventional ultrasound with AR and ESR, which were superior to combining with the other parameters and provide a more objective and credible basis to differenti-ate benign and malignant breast tumors with conventional ultrasound.

This study was aimed to investigate allergic reactions of traditional Chinese medicine (TCM) injections, and to determine contents of serum IgE in sensitized animals. The correlation between preceding contents in serum and allergic reactions may be found, in order to offer experimental evidences for advancing the accuracy of anticipa-tion by allergic reactions. Passive cutaneous anaphylaxis (PCA) tests and anaphylactoid reactions were used in a vari-ety of TCM injections. ELISA method was used to determine the content of total serum IgE in sensitized animals. The PCA results of SHL, QKL, YXC, XST, GGS and CHN were negative. The PCA result of CWJ was positive. There was no significant difference for total serum IgE level between the experimental group and the normal saline group in the group of SHL, QKL, YXC, XST, GGS, CHN and CWJ. All TCM injections caused anaphylactoid symp-toms in guinea pigs. It was concluded that all TCM injections can cause allergic reactions in guinea pig. And the al-lergic reactions of TCM injections were not correlated with serum total IgE.

Objective To compare enteral nutrition (EN) and total parenteral nutrition (TPN) in the treatment of severe acute pancreatitis(SAP) elucidate the advantage of EN. Methods Fifty-nine patients were assigned to TPN and EN groups. The nutritional index was detected, and the therapeutic efficacy was reviewed comparetively. Results After giving the nutritional support, the serum contents of albumin, pre-albumin, transferrin and beamoglobin were increased obviously (P < 0.05);and prealbumin, transferrin had statistical difference between the TPN and EN groups(P <0.05). APACHE Ⅱ score was lowered significant-ly in the EN group, comparing with the TPN group (P <0.05). In the EN group, complications, infection rate, food intake time, and hospitalization costs were significantly lower compared with the TPN group(P< 0.05), although mortality rate, hospital stay days had no statistical significance (P > 0.05). Conclusion EN is on ideal modality of nutrition support in SAP patients, which has many advantages in improving nu-tritional status, preserving gut mucosa barrier, decreasing bacterium and toxin shifting, regulating inflamma-tory and infective response, decreasing costs in the hospital.
