Objective To explore the clinical application value of duodenum-preserving total pancreatic head resection by modified Takada procedure in the treatment of pancreatic head lesions.Methods Thc clinical data of 6 cases of modified Takada duodenum-preserving total pancreatic head resection in Zhangzhou Affilicated Hospital of Fujian Medical University and Zhangzhou Zhengxing Hospital from Sep 2013 to Sep 2014 was retrospectively analyzed.Results The mean operative time was (281.7 ± 42.6) minutes,the mean intraoperative blood loss was (300 ± 187) ml.The mean time to recovery to oral food-intake was (3.7 ± 1.6) days.Average length of hospital stay after operation was (9 ± 4.3)days.Of these cases,all preserved duodenal papilla and Vater ampulla and one-stage end-to-end anastomosis of the pancreatic duct in situ was done.Postoperative complications developed in 2 cases,one was pancreatic leakage and other one was bile leakage,all were cured conservatively.No perioperative deaths occurred.Postoperative pathology proved chronic pancreatitis in 3 cases and primary pancreatic tumors in another.3 Follow-up time ranged from 6 to 17 months,median was 13 months.There was no case of recurrence.Conclusions The modified Takada duodenum-preserving total pancreatic head resection removes pancreatic head where the lesion lies totally.One-stage end-to-end pancreatic duct reconstruction in situ is safe,ensuring fast and uneventful recovery.

BACKGROUND:Self-made Distraction Reduction Fixation System is characterized by Distraction Reduction Fixation functions,which can completely fuse to the design of steel plate,and by no need to provide many surgical instruments,by reduction of bleeding and trauma.OBJECTIVE:To test changes in the stiffness of porcine short spinal segments in integrity and following destabilizing and internal fixation of the Distraction Reduction Fixation System.DESIGN,TIME AND SETTING:The control observation experiment was performed at the Laboratory of Biodynamics,Institute of Onhopedics,General Hospital of Chinese PLA from December 2004 to December 2005.MATERIALS:Twelve fresh porcine lumbar spines(T11-S2 segments)were bought from a market.Upper and lower segments were crossed and inserted with Kirschner wire to make porcine spine samples of the L1-7 segments.METHODS:Stiffness of intact samples was recorded during forward-bending,backward-bending,lateral-bending and axial rotation.Intervertebral discs,facet ioints,anterior and posterior longitudinal ligaments were removed to loose the spine.Stifrness of each motion was measured.Stiffness tests were repeated again after internal fixation on short segments using Distraction Reduction Fixation System.MAIN OUTCOME MEASURES:Stiffness in the intact,unstable and internal fixed spines during each motion.RESULTS:The stiffness iu unstable porcine spine were significantly lower than those in intact porcine spine(P<0.05),but the stiffness after internal fixation was significantly higher than in unstable porcine spine(P<0.05).No significant difference was detected in stifiness during forward-bending,lateral-bending and axial rotation(P>0.05)except that it was significantly higher during backward.bending after internal fixation compared with the intaet spine(P<0.05).CONCLUSION:Biodynamics confirms that the stiffness in short-segment fixation porcine after using Distraction Reduction Fixation System is markedly increased than in unstable porcine spine,except during backward-bending,which is comparable with that in intact porcine spine.

Objective To know the correlation about PetCO_2 and PaCO_2, the meanings of PetCO_2monitoring in respiratory failure patients with mechanical ventilation, and then summarize the related nurs-ing points. Methods Divided 112 patients in ICU into the A group(58 eases) and the B group(54 cas-es) according to their station of hemodynamics. Mechanical ventilation were used in both the two groups,PetCO_2 and PaCO_2 were monitored at the same time, and then observed the correlation of PetCO_2 and Pa-CO_2 in both the two groups. Results There was a significant corrlation in the A group about PetCO_2 and PaCO_2, while the correlation in the B group was not significant. Conclusions PetCO_2 and PaCO_2 had sat-isfactory corrlation in patients with stable hemedynamies, PetCO_2 monitoring can take place of PaCO_2 in these patients with its sensitive, atraumatic, consecutive and convient merits.

Objective: To explore the relationship between expressions of estrogen (ER) and progesterone (PR) receptors and syndromes of traditional Chinese medicine (TCM) in gastric carcinoma and to establish prognostic indicators for gastric carcinoma. Methods: A total of 72 patients with gastric carcinoma were divided into six groups according to TCM syndrome differentiation. Specimens were collected after operation and ER and PR protein expressions were detected by EnVision immunohistochemical method. Results: The common syndromes in female patients with gastric carcinoma were disharmony between liver and stomach, yin impairment due to stomach heat, and insufficiency of both qi and blood; while in males, interior retention of stagnant toxin, interior retention of phlegm and dampness, and deficiency-cold in spleen and stomach were common. Different TCM syndromes were related with gender (P<0.01), pathology (P<0.01), cell differentiation (P<0.05), infiltration depth (P<0.01), lymphaden metastasis (P<0.05), distant metastasis (P<0.05), and TNM stage (P<0.01). Deficiency and excess syndromes were associated with gender (P<0.05), pathology (P<0.05), tumor location (P<0.01) and TNM stage (P<0.05). The deficiency syndromes were common in female patients. The total positive rates of ER and PR expressions were 8.33% and 37.5% respectively. There was a significant difference in PR expression among different TCM syndromes (P<0.01). PR expression was significantly higher in the syndrome of yin deficiency due to stomach heat than in the other syndromes. The PR expressions in deficiency syndromes were significantly higher than those in excess syndromes (P<0.01). No correlation was found between ER expression and different TCM syndromes. Conclusion: There is a correlation between PR expression and different TCM syndromes in gastric carcinoma.

Objective To evaluate the results of hybrid procedure in treating infants and children with severe pulmonary stenosis (PS) and the clinic value of echocardiography in the whole procedure.Methods Hybrid therapy was performed in 43 patients [(7.1±6.8)months,ranging 5 days to 33 months] with severe PS.The echocardiography data in the whole procedure and follow up were reviewed.Results Aided by echocardiography,the hybrid therapy was successful in 43 cases without major complication.Immediately following valvuloplasty,the gradient across pulmonary valve decreased from (92.5±21.4)mm Hg to (23.6±13.0)mm Hg (P<0.05).The growth and development of 27 patients in follow-up study was well.No restenosis was found and tricuspid regurgitation decreased differently.Conclusions Hybrid procedure is effective and safe for the treatment of infants and children with severe PS.And echocardiography play an important role in the whole procedure.

Objective To investigate CT,clinical and pathological features of primary pulmonary lymphoepithelioma-like carcinoma (LELC). Methods The clinical,CT and pathological data of 22 patients with pulmonary LELC confirmed by pathology were analyzed retrospectively, including 8 males and 1 4 females whose ages were from 1 8 to 88 years old.Results Among 22 cases,1 2 patients were found by physical examination,2 patients had cough and sputum,7 patients had cough hemoptysis and 1 patient was found by re-examination after breast cancer surgery.On CT,all cases manifested single mass in the lung,and the longer diameters ranged from 1.5 cm to 1 1 cm,in which there were central type tumors in 8 cases and peripheral type tumors in 14 cases.Nineteen masses showed homogeneous density in non-enhanced scan,and the cavity,irregular calcification and small patchy necrosis were seen in each 1 case.After contrast-media injected,masses were mild-moderately or evidently enhanced in 7 cases and 1 5 cases respectively.Eighteen cases had well defined border and unclear border in 4 cases.Vascular encasement were found in 6 central type tumors,8 tumors squeezed peripheral vascular and 8 cases had clear demarcation between tumors and vascular.Nineteen tumors were surgically removed,in which 7 cases appeared metastasis of lymph node.Histopathology showed that the tumor cells had large volumes,unclear boundaries,large nuclei,growing in syncytial nest-like patches.There were abundant lymphocyte and plasma cell infiltration in tumor’s mesenchyma.EBER were done in 1 6 cases and the results were all positive.Conclusion CT feature of pulmonary LELC manifestes that the masses are mostly single,large size, homogeneous density,clearly boundary,shallow lobulated and significantly enhancement.Vascular encasement is the feature of central pulmonary LELC,and peripheral LELC is more likely to occur in the sub-pleural region.Final diagnosis should be combined with clinical and pathological diagnosis.

OBJECTIVE: To investigate the association of the time of initial diagnosis with the severity of chronic obstructive pulmonary disease (COPD). METHODS: A total of 803 patients who were diagnosed to have COPD for the first time in our hospital between May 2015 to February 2018 were enrolled in this study.The diagnoses of COPD and asthma COPD overlap (ACO) were made according GOLD guidelines and european consensus definition.Lung function of the patients was graded according to the GOLD guidelines. RESULTS: The patients with COPD had a mean age of 61.8±9.9 years,including 726 male and 77 female patients.The course of the patients (defined as the time from symptom onset to the establishment of a diagnosis) was 3(0.5,8) years.Among these patients,85.2% had a moderate disease severity (FEV1%<80%),and 48.3% had severe or very severe conditions (FEV1%<50%);47.0% of them were positive for bronchial dilation test.In the overall patients,295(36.7%) were also diagnosed to have ACO,and the mean disease course of ACO[3(1,9) years]was similar to that of COPD[3(0.5,8) years](>0.05).A significant correlation was found between the disease course and the lung function of the patients.Multiple linear regression analysis showed that an older age and a longer disease course were associated with poorer lung functions and a greater disease severity. CONCLUSIONS The delay of the initial diagnosis is significantly related to the severity of COPD.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
