ObjectiveTo investigate the distribution and drug resistance of pathogens in neonates with lower respiratory tract infection, and provide evidence for clinical rational antibiotic use. MethodsA retrospective analysis on 998 strains isolated from 5 486 sputum samples during January 1, 2009 to December 31, 2012 collected from hospitalized neonates was performed. ResultsOf the 998 isolated strains, the common pathogens were Klebsiella pneumoniae (23.1%), Escherichia coli (E. coli) (21.2%), Staphylococcus aureus (19.4%), and Enterobacter cloacae (8.4%). Klebsiella pneumonia, E. coli and Enterobacter cloacae were generally resistant to penicillin, but enzyme inhibitors could reduce the resistance rate. A large proportion of Klebsiella pneumonia was resistant to the third generation cephalosporins (78.4%), while E. coli and Enterobacter cloacae had a lower resistance rate (46.7% and 46.5%, respectively). There were 7 strains (3.0%) of Klebsiella pneumoniae and 1 (1.2%) strain of Enterobacter cloacae resistant to imipenem. Twenty-three strains (13.6%) of Klebsiella pneumoniae, 1 strain (0.7%) of E.coli and 1 strain (2.5%) of Enterobacter cloacae were resistant to ertapenem. A total of 97.0% of Staphylococcus aureus was resistant to penicillin, but only 11.0% was resistant to oxacillin, and all the isolates were sensitive to vancomycin. ConclusionGram negative bacteria are the common pathogens in the hospitalized neonates in our hospital. Klebsiella pneumonia, E. coli and Staphylococcus aureus are the common pathogens. The common pathogens show a high resistant level to antibiotics. Clinicians should evaluate the potential pathogens of infections based on the results presented in our study, in order to select antibiotics rationally when treating infections.
Objective?To investigate the relationship between syndromes of traditional Chinese medicine (TCM) and lung function in patients with chronic obstructive pulmonary disease (COPD) at stable phase. MethodsBased on diagnostic criterion of TCM, five groups of symptoms of TCM about stable COPD were established including lung Qi deficiency, lung and spleen Qi deficiency, lung and kidney Qi deficiency, lung Spleen Kidney Qi deficiency, and deficiency of both Qi and Yin. A total of 300 cases which were up to the standard were differentiated into 5 groups by the symptoms. Some basic details and lung function of the patients were recorded, and then statistical analysis was performed to analyze the differences of lung function among groups. ResultsForced expiratory volume in the first second in descending order was lung Qi deficiency group, lung and spleen Qi deficiency group, lung and kidney Qi deficiency group, and lung spleen kidney Qi deficiency group (P<0.05). ConclusionThese findings suggest that with the progressing of COPD, the symptom type of TCM for COPD patients at stable phase may vary from lung Qi deficiency to lung and spleen Qi deficiency, or to lung and kidney Qi deficiency, and even lung, spleen and kidney Qi deficiency. Lung function tests help reveal substance and pathogenesis of TCM syndromes of patients with stable COPD, and provide evidence for the clinical syndrome.
ObjectiveTo investigate the clinical effect and mechanism of Chinese heat-clearing and phlegm-resolving recipe in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MethodsA randomized controlled trial (RCT) was conducted. A total of sixty in-patients with AECOPD of phlegm heat and phlegm turbidity in lungs were randomly allocated to treatment group and control group with an equal number of patients between October 2009 and March 2010. The treatment duration was 10 days. Symptom scores of traditional Chinese medicine (TCM), pulmonary function, white blood cell count, polymorphonuclear neutrophils, C-reactive protein and the plasma concentration of bactericidal/permeability increasing protein (BPI) and interleukin (IL)-8 and IL-10 were detected. ResultsFor TCM syndrome of phlegm heat and phlegm turbidity, there was a statistical difference between the two groups after treatment (P<0.05). Cough, sputum amount, expectoration and coated tongue were improved obviously in the treatment group (P<0.05). The total explicit efficiency rate and effective rate were 56.0% and 84.0% in the control group and 82.1% and 92.9% in the treatment group respectively. The total explicit efficiency rate was significantly different between the two groups (P<0.05), while the total effective rate was not significantly different (P>0.05). Plasma concentration of IL-8 decreased markedly in the treatment group and IL-10 and BPI increased obviously. There was no significant difference in the change of BPI, IL-8 between the two groups (P>0.05), except for IL-10 (P<0.05). ConclusionChinese heat-clearing and phlegm-resolving recipe can improve signs and symptoms of TCM in the treatment of AECOPD (phlegm heat and phlegm turbidity in lungs), by the potential mechanism of increasing the level of IL-10.
ObjectiveTo evaluate the effectiveness of arthroscopic treatment of superior labrum anterior and posterior (SLAP) injury by absorbable anchors through anterior and posterior approach. MethodsBetween January 2010 and August 2012, 28 patients with Snyder II type of SLAP injury underwent arthroscopic operation by absorbable anchors through anterior and posterior approach. There were 15 males and 13 females, aged from 30 to 45 years (mean, 36.5 years). The left shoulder was involved in 12 cases and the right shoulder in 16 cases. All patients had a clear history of trauma. The disease duration ranged from 2 weeks to 3 years (median, 13 months). The results of O'Brien test and Speed test were positive in 25 cases and 26 cases respectively. Shoulder pain visual analogue scale (VAS) was 7.6±1.4. The Constant score of shoulder joint function was 60.2±4.3. ResultsOperation was successfully completed, and the incision healed well in all cases, with no complication. The follow-up time ranged from 12 to 36 months (mean, 24.5 months). The symptoms of shoulder joint interlocking, snapping, and instability disappeared. The joint pain was significantly improved. At 12 months after surgery, Constant score of shoulder joint function was 92.7±4.5, showing significant difference when compared with preoperative score (t=-30.279, P=0.000); the shoulder pain VAS score was 1.1±0.9, showing significant difference when compared with preoperative score (t=23.810, P=0.000). At 1 year after operation, MRI examination showed complete healing in 25 cases, and high signal in 3 cases, but the pain and activity were significantly improved. ConclusionArthroscopic treatment of SLAP injury by absorbable anchors through anterior and posterior approach has the advantages of less injury, small incision, and quick recovery, so it is an ideal operation method.
ObjectiveTo investigate the decision of combined liver and kidney transplantation (CLKT) after renal transplantation, provide surgical therapeutic experience for those patients with liver and renal insufficiencies and hepatorenal syndrome and summarize the risk factors, demerits and merits, and operative indications of CLKT. MethodsThe data of three successful CLKT cases of our centre from Feb. 2014 to Jan 2015 were retrospectively analyzed, and these three patients had kidney transplantation before. We also reviewed the latest associated literatures. ResultsThree patients got successful operations of CLKT and had very good recovery of renal function several days ofter operaton. Two of them discharged a few weeks after surgery, and one of these two patients got severe pulmonary infection of fungus two month after CLKT but recovered under proper therapy finally. The third patient died of severe mixed infection one month after CLKT. ConclusionsThe surgical techniques and rejection are not the main impact factor to the prognosis of CLKT after renal transplantation. Infection is the biggest trouble to which we should pay most of our attention. We should decide whether to do synchronous or nonsynchronous CLKT according to the situation before surgery. Moreover, the systematic therapy administration after CLKT is very necessary for the patients' long-term survival.
ObjectiveTo investigate the ideal digestive tract reconstruction method for radical distal gastrectomy (DG). MethodsClinical and follow-up data of 862 patients with gastric cancer who underwent DG in Xijing Hospital of Digestive Diseases of The Fourth Military Medical University from January 2010 to January 2013 were analyzed retrospectively. According to reconstruction methods, patients were divided into three groups:Billroth Ⅰ group (B-Ⅰgroup), Billroth Ⅱ (B-Ⅱ)+Braun group (B-Ⅱ+Braun group), and Roux-en-Y group. In order to reduce the difference of clinicopa-thological characteristics, Gmatch method was used to select patients basing on gender, age (±5 years), tumor size (±1 cm), pT staging, and pN staging. The perioperative data, recent (30 days after surgery) complications, gastroscopic results over one year, and postoperative survival rate were compared respectively among the 3 groups. Results① Perioperative indexes. The operative time, postoperative hospitalization, and semi liquid diet time were significantly different among 3 groups (P < 0.050). As compared with B-Ⅱ+Braun group and Roux-en-Y group, B-Ⅰ group had a significantly shorter operative time (P < 0.012 5), and there was no significant difference between B-Ⅱ+Braun group and Roux-en-Y group (P > 0.012 5). As compared with B-Ⅱ+Braun group, B-Ⅰ group had a significantly shorter semi liquid diet time (P < 0.012 5), but there was no significant difference between B-Ⅱ+Braun group and Roux-en-Y group, as well as Roux-en-Y group and B-Ⅰ group (P > 0.012 5). As compared with B-Ⅰ group and B-Ⅱ+Braun group, Roux-en-Y group had a significantly longer postoperative hospitalization (P < 0.012 5), and there was no significant difference between B-Ⅰ group and B-Ⅱ+ Braun group (P > 0.012 5). ② There was no significant difference in recent complications between Roux-en-Y group (12.5%, 4/32), B-Ⅱ+Braun (6.2%, 2/32), and B-Ⅰ group (3.1%, 1/32), P=0.495. ③ Results of endoscopic examination over 1 year after radical DG showed that there was significant difference among 3 groups (P < 0.050). Compared with B-Ⅰ group and B-Ⅱ+Braun group, the rates of reflux gastritis, bile reflux, and reflux esophagitis of Roux-en-Y group were all lower (P < 0.012 5), but there was no significant difference between B-Ⅰ group and B-Ⅱ+Braun group (P > 0.012 5).④ The 3-year survival rates of Roux-en-Y group, B-Ⅱ+Braun group, and B-Ⅰ group were 70.0% (21/30), 73.3% (22/30), and 75.0% (24/32) respectively, and there was no significant difference in the survival situation (P=0.911). ConclusionsThe effect of Rouxen-Y anastomosis on resisting gastrointestinal reflux is remarkable. B-Ⅰanastomosis has the advantages of more simple operation, faster recovery, and more similar to the physiological structure. Thus, B-Ⅰ anastomosis and Roux-en-Y anastomosis are recommended for digestive tract reconstruction in DG.
