The development of HIS and the isolation of all the HISs are mentioned in this paper. It's suggested that HL7 be used to unify the health information. The inosculation of Laboratory Information System (LIS) and Hospital Information System (HIS) is taken as an example to introduce a unification scheme of medical treatment information network based on Health Level Seven (HL7) Engine.

Information integration of heterogeneous systems needs implementing to meet the communication requirements of all subsystems of Hospital Information System (HIS). The solution is to introduce Health Level Seven (HL7), an international medical information exchange standard. With extensible Markup Language (XML) as the message-encoding manner, HL7 version 3 follows the object-oriented methodology. Based on the message system of HL7 version 3, this paper introduces an XML-based message processing technology and then testifies its feasibility.

OBJECTIVE:To study the protective effects of Baimai ointment on sciatic nerve injury in rabbit. METHODS:The rabbit sciatic nerve injury model was induced by forceps operation. 180 rabbits were randomly divided into 6 groups,with 30 rab-bits in each group (10 rabbits of 7,14,28 d),including sham operation group (blank matrix of Baimai ointment for external use),model group(same as sham operation group),positive group [ig Mecobalamine tablet solution 1.25×10-4 g/(kg·d)] and Bai-mai low-dose,medium-dose and high-dose groups [Baimai ointment 0.33,0.67 and 1.34 g/(kg·d)for external use],once a day, for consecutive 7,14 and 28 d. Gait instrument was used to test the foot-touch-land force of rabbit;pathology examination was conducted for sciatic nerve resection;immunohistochemistry was used to detect the levels of NOS and NMDA in nerve tissue. RE-SULTS:Baimai ointment can significantly relieve sciatic nerve injury,edema and inflammatory reaction;7,14 and 28 d after med-ication,compared with model group,foot-touch-land force decreased significantly in rabbits with sciatic nerve injury (P<0.01);14,28 d after medication,foot-touch-land force of rabbits increased significantly in positive group,Baimai ointment groups,while the levels of NOS and NMDA decreased in nervous tissue(P<0.05). CONCLUSIONS:Baimai ointment can protect sciatic nerve with function injury in rabbits.

ObjectiveTo explore the effect of combined usage of expanding coronal decompressive craniectomy and sequential dural incision for treating severe bilateral frontal contusion (SBFC).Methods Forty-three patients with SBFC were randomly divided by sequential single day after hospitalization into two groups.Observation group(23 cases) treated with expanding coronal decompressive craniectomy and sequential dural incision.Control group (20 cases) treated with standard hemicraniectomy and routine dural incision.ResultsThe occurrence rate of acute cephalocele was significantly lower in observation group [ 17.4％(4/23) ] than that in control group [ 55.0％(11/20) ] (P ＜ 0.05).According to Glasgow outcome scale (GOS) score of six-month observation after operation,17 cases(73.9％,17/23) of observation group got favourable recovery or moderate deficit,other 6 cases(26.1％,6/23) got severe deficit,persistent vegetative status or death.While only 8 cases(40.0％,8/20) got favourable recovery or moderate deficit,12 cases ( 60.0％,12/20 ) got severe deficit,persistent vegetative status or death in control group.The rate of favourable recovery and moderate deficit of two groups had statistical significance (P ＜ 0.05).ConclusionCombination application of expanding coronal decompressive craniectomy and sequential dural incision is an effective method to treat patients with SBFC,and can obviously improve the rate of successful rescue and decrease the rate of mortality and disability.

PURPOSE: Traditional chemotherapy is the main adjuvant therapy for the treatment of non-small cell lung cancer (NSCLC). However, the emergence of multi-drug resistance (MDR) has greatly restricted the curative effect of chemotherapy. Therefore, it is necessary to find a method to treat MDR NSCLC clinically. It is worth investigating whether NSCLCs that are resistant to traditional chemotherapy can be effectively treated with tyrosine kinase inhibitors targeting epidermal growth factor receptor (EGFR). MATERIALS AND METHODS: The expression of P-glycoprotein (P-gp) and lung resistance-related protein (LRP) was detected by immunohistochemistry, and mutations in EGFR (exons 19 and 21) and Kirsten rat sarcoma viral oncogene homolog (KRAS) (exon 2) were detected by high-resolution melting analysis (HRMA) of surgical NSCLC specimens from 127 patients who did not undergo traditional chemotherapy or radiotherapy. A Pearson chi-square test was performed to analyze the correlations between the expression of P-gp and LRP and mutations in EGFR and KRAS. RESULTS: The expression frequencies of P-gp and LRP were significantly higher in adenocarcinomas from non-smoking patients; the expression frequency of LRP was significantly higher in cancer tissue from female patients. The frequency of EGFR mutations was significantly higher in well to moderately differentiated adenocarcinomas from non-smoking female patients. The frequency of EGFR mutations in the cancers that expressed P-gp, LRP, or both P-gp and LRP was significantly higher than that in cancers that did not express P-gp or LRP. CONCLUSION: NSCLCs expressing P-gp/LRP bear the EGFR mutation in exon 19 or 21 easily.

Objective To provide a method to modify accurately the Reverdin osteotomy template for hallux valgus using 3D reconstruction and printing.Methods From June 2015 to June 2016,11 patients (16 feet) with hallux valgus at our departments underwent weight-bearing X-ray examination and continuous spiral CT scanning of the feet.The outer turning angle of hallux averaged 33.50° ± 6.80°,the first intermetatarsal angle 12.20°± 2.90° and the distal metatarsal articular angle 15.20°± 2.60°.Their imaging Dicom data were imported into Materialise Mimics Innovation Suite v16.0 software for generation of 3D models of the pelvis which were then stored in stereolithography format and imported into Imageware 12 software.After optimal templates were reversely rebuilt to have the best angles and range for Reverdin osteotomy in the 3D models,they were manufactured by a rapid prototyping machine.The osteotomy templates were used in surgery to guide the osteotomy of hallux valgus.Correction of hallux valgus,bone union at the osteotomy sites and weight-bearing walk were observed postoperatively.Results Accurate angles of osteotomy were confirmed by postoperative radiography in all the 16 feet.Follow-ups for 6 to 12 months showed in the 16 feet a mean outer turning angle of hallux of 7.31 °±0.33° (from 5° to 11 °) and a mean correction of 21.92°± 4.8° (from 13° to 24°).Bone union was fine at the osteotomy sites and no pain was reported during weight-bearing walk.Conclusion 3D reconstruction and printing can produce a patient-specific template for accurate Reverdin osteotomy for hallux valgus,leading to increased contact area and fine union of the osteotomy ends.

OBJECTIVE: Segmented cardiac cine magnetic resonance imaging (MRI) is the gold standard for cardiac ventricular volumetric assessment. In patients with difficulty in breath-holding or arrhythmia, this technique may generate images with inadequate quality for diagnosis. Real-time cardiac cine MRI has been developed to address this limitation. We aimed to assess the performance of retrospective electrocardiography-gated real-time cine MRI at 3T for left ventricular (LV) volume and mass measurement. MATERIALS AND METHODS: Fifty-one patients were consecutively enrolled. A series of short-axis cine images covering the entire left ventricle using both segmented and real-time balanced steady-state free precession cardiac cine MRI were obtained. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), and LV mass were measured. The agreement and correlation of the parameters were assessed. Additionally, image quality was evaluated using European CMR Registry (Euro-CMR) score and structure visibility rating. RESULTS: In patients without difficulty in breath-holding or arrhythmia, no significant difference was found in Euro-CMR score between the two techniques (0.3 ± 0.7 vs. 0.3 ± 0.5, p > 0.05). Good agreements and correlations were found between the techniques for measuring EDV, ESV, EF, SV, and LV mass. In patients with difficulty in breath-holding or arrhythmia, segmented cine MRI had a significant higher Euro-CMR score (2.3 ± 1.2 vs. 0.4 ± 0.5, p < 0.001). CONCLUSION: Real-time cine MRI at 3T allowed the assessment of LV volume with high accuracy and showed a significantly better image quality compared to that of segmented cine MRI in patients with difficulty in breath-holding and arrhythmia.
