After serious-minded analyzing on the former service process,the manager of our hospital found the problems in the old construction and considered more reasonable design in the new service building.The patient-centered new outpatient building was aimed to meet patient's needs,improve service quality,allocate medical resource,innovate new pattern and optimize the work process.It will provide a bright future for the development of hospital.

Objective To develop a complete set of medical water processing and supply system to meet the needs of water in field operations for emergency rescues and disaster relief work, filed advance drill, etc. Methods A complete set of medical water processing and supply system was composed of two parts, including water processing system and water supply system. The means of filtrating, precipitating, sterilizing, adsorbing and ion regulating were adopted in water processing system to purify the water from primitive and to pure state for living or medical treatment. The techniques and equipments such as pressurizing, buffering, current regulating and special pipes, valves, fast joints, etc, were adopted in water supply system, and high performance water-pipe network were established. Results The water processing and supply system has some disadvantages, such as water quality guarantee, water quantity abundance, water flow stabilization, water pressure qualification, and system safety, credibility, low failure-ratio, energy saving etc, and can meet the needs of medical water in field operations. Conclusion The water system can be carried out by design optimizing and can realize mobile and emergencies.

Objective To assess the effectiveness of the Chinese herbal formula Tongxie Yaofang(TY) or its modified prescriptions in the management of irritable bowl syndrome(IBS).Methods A systematic review was carried out according to the Cochrane standards.A computerized literature search was carried out in main Chinese and English databases including CNKI,CBMdisc,Database of Chinese Doctorate Dissertation,Database of excellent Chinese Master Dissertation,MEDLINE and Cochrane Library.Studies were retrieved when they were randomized controlled trials(RCTs) whose interventions for IBS patients were TY or modified prescriptions of TY with placebos or conventional medicine as controls.Outcome measurement included the alleviation of main symptoms such as abdominal pain,diarrhea frequency,and(or) comprehensive effectiveness and quality of life(QOL).Meta-analysis was performed after evaluating the quality of included studies.Subgroup analysis was done between subgroups of diarrhea-predominant IBS and subtype-regardless IBS,and was also done between diarrhea-predominant IBS treated with TCM syndrome differentiation and that without TCM syndrome differentiation.Funnel plot analysis was used to analyze the publication bias.Results Forty-six studies met the inclusion criteria,and 4155 participants were included in the meta-analysis.The results showed that the effectiveness of TY or modified prescriptions of TY was better than that of conventional medicine or placebos[OR= 5.30,95%CI(4.38,6.41)].Subgroup analysis showed that the OR of TY or modified prescriptions of TY in the diarrhea-predominant groups[OR=5.61,95%CI(4.33,7.25)]was higher than that of subtype-regardless groups[OR=4.95,95%CI(3.74,6.55)],and OR of TY or modified prescriptions of TY in the studies of diarrhea-predominant IBS treated based on TCM syndrome differentiation [OR=6.50,95%CI(3.78,11.20)] was higher than that of the studies without TCM syndrome differentiation[OR=5.37,95%CI(4.01,7.19)],but the difference was insignificant.Funnel plot showed certain publication bias.Conclusion The effectiveness of TY or modified prescriptions of TY for IBS patients is better than that of western medicine and placebo.But their effectiveness for diarrhea-predominant IBS or with TCM syndrome differentiation was not proved to be better than those for other subtypes or without TCM syndrome differentiation.Biases may exist for overall quality of the studies is low;negative results in some high quality studies need further discussion.

Objective: To evaluate the application of frontal flap in reconstructing the defect of nose, the clinical data of 12 cases were reported. Methods: Twelve patients with nasal skin cancers undertaking radical dissection of tumor accompanied frontal flap reconstructing one stage were reviewed retrospectively.Results: The overall following\|up rate was 100%, 10 of these patients curled slightly after reconstructing the nose, but influence of the nasal outline was little. Two cases were recurrent locally, one occurred 24 months after operation, the other occurred 38 months. Both of them received radiotherapy. Malformation arised after radiotherapy. The total successful rate of reconstruct nasal outlook was 83.33%, the 3\|year locally recurrent rate was 8.33%,5\|year survival rate ws 100%, 5\|year survival rate without tumor was 83.33%.Conclusion:The blood supply of frontal flap is abundance;healing up soon after reconstruction; the manipulation of surgery is simple and safe. It is worth applying this operation generally in clinical practice.

Chronic kidney disease (CKD) is becoming a global social problem. It is important to slow down the progression of CKD for economic and social concerns. In recent years, it has been found that colon is one of the vital organs which produce uremic toxins. And enterogenous uremic toxins are closely related to the prognosis of CKD. Theory of gut-kidney axis for the slowdown of CKD progression was raised by foreign scholars and became the research hot spot. Colon therapy with traditional Chinese medicine (TCM) has been widely used in clinical practice and is believed to slow down the progression of CKD by numerous clinical reports. However, low re-search quality and ambiguous results limited its further application. Under the guidance of senior TCM Professor Huang Chunlin, who emphasized the method of draining turbidity through bowels in the management of CKD, from the Nephrology Center, Guangdong Provincial Hospital of Chinese Medicine, as well as the modern theory of gut-kidney axis, we had carried out a series of exploratory researches which will provide data and methodology support for further confirmatory studies and improve its effectiveness.

Objective:To investigate the application of 3D printing technique in percutaneous nephrolithotomy (PCNL) of patients with complicated kidney stones.Methods:From January 2015 to December 2017, 60 patients with complicated kidney stones were enrolled in the First Affiliated Hospital of Hebei North University for prospective study, and PCNL was proposed.All the patients were randomly divided into 3D print group (30 cases) and conventional image inspection group (30 cases, control group). Before operation, CT urography (CTU) was used in both groups.In 3D printing group, digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image postprocessing, and thermoplastic materials were used to print 3D model.In the 3D printing group, the digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image post-processing, and the 3D model was printed with thermoplastic materials.According to the comprehensive planning of 3D kidney model, a virtual safe and reliable percutaneous renal access was established for each patient, and PCNL was executed.The patients in the two groups were compared before, during and after operation.Preoperative: age, sex, body mass index, blood creatinine, stone size and CT value.During the operation: (1) the target renal calices location time; (2) the conformity between the preoperative planning and the actual operation; (3) the operation completion time.After operation: (1) stone removal rate; (2) hemoglobin reduction level; (3) postoperative recovery.Results:All the 60 patients successfully completed the operation, 30 patients successfully printed out the 3D model, which can accurately express the relationship between the stone and the adjacent anatomical structure, the internal renal artery and the collecting system.Positioning time of 3D printing group in target renal calices((2.9 ± 1.5) min vs.(5.8 ± 1.7) min, P=0.023), coincidence between simulated and actual puncture calices((89.5 ± 3.5)% vs.(60.2 ± 5.7)%, P=0.005), postoperative stone removal rate ((89.9 ± 4.5)% vs.(75.9 ± 5.2)%, P=0.009), and hemoglobin levels((1.4 ± 0.5) g/L vs.(2.9 ± 1.4) g/L, P=0.032) were superior to the control group, and the difference was statistically significant.But there was no significant difference between the two groups (all P>0.05). Conclusion:The 3D printed kidney model truly restores the anatomical details around the kidneys and stones, providing a stereoscopic and intuitive way to perform surgery, so it maybe has a significance guidance for percutaneous nephrolithotomy.
