OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.

METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.

RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).

CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.

Using the high efficient copper-adsorbing yeast strain Y17 as absorbing material, the major affect factors including pH, original concentration of Cu2+, cell biomass, adsorption time and temperature were examined, and then the absorbing sites of the Y17 was determined. The results showed that the solution pH was the most dominate factor which affected the biosorption of Cu2+, the other affecting factors were the ini- tial concentration of Cu2+, the cell biomass added, and adsorption time, respectively; the temperature had lit- tle effect on the rate of biosorption. The orthogonal experiment showed that the optimal absorption condition was as follow: the solution pH was 5.0, the absorption time was 40 min, the cell biomass of Y17 added was 5.0 g/L, and the concentration of Cu2+ was 8 mmol/L; the highest adsorbing rate was up to 82.7% at this condition. Based on the results of different pretreatments and the desorption of Cu2+, the cell wall of Y17 was identified as the main place occurring boisorption process, and the -NH2 group, -COOH group on the surface of the yeast cells played an important role on the boisorption process.

A total of 200 outpatients with congenital urogenital abnormalities were recruited.Peripheral blood from each patient had mixed lymphocyte culture and chromosome karyotype was analyzed.Among them,22 (11％) cases showed abnormal chromosomal karyotypes.The aberrations included abnormal chromosome number (n =13),abnormal chromosome structure (n =8) and sex reversal syndrome (n =1).Chromosomal aberrations are important causative factors of congenital urogenital abnormalities.

Objective To explore the spiral computed tomography (CT) imaging feature of post-intubation tracheal stenosis (PITS) and to discuss its clinical significance. Methods The clinical data and CT imaging findings of 27 patients with PITS were retrospectively analyzed. The location, degree and shape of PITS were analyzed, and the imaging features were summarized. Based on the imaging features the etiology of PITS was suggested, and the role of imaging feature in assessing PITS condition and in planning clinical management was evaluated. Results A total of 35 tracheal strictures were detected in the 27 patients. The location of the strictures included trachea incision site (n=10), balloon level (n=5) and distal end of tube (n = 20). In all patients the degree of stenosis was > 30%. Localized stenosis was seen in 15 cases, which presented as “hourglass”or “girdle”shape. Segmental stenosis was found in 4 cases, which was characterized by a “ribbon” or “dumbbell” stricture on CT scans. Complex stenosis was found in 8 cases. With the help of imaging findings, all patients got timely, proper and individualized treatment. Conclusion PITS has typical imaging characteristics. Spiral CT scanning should be regarded as the imaging examination of first choice. Based on the different imaging characteristics, the relevant departments can evaluate patient’s condition and make individualized treatment plan. The imaging finding is very helpful for anesthesiologists and other clinicians in recognizing and in managing the post-intubation tracheal stenosis.

Objective To discuss the ventilatory catheter-assisted airway stenting under local anesthesia for airway stenosis.Methods From May 2008 to January 2013,25 consecutive patients with airway stenosis underwent the treatment of ventilatory catheter-assisted airway stenting under local anesthesia.The dyspnea score was grade Ⅱ in 3 patients,grade Ⅲ in 18 patients and grade Ⅳ in 4 patients.During the treatment,a 4 F VER catheter was placed into one of the main bronchi as a ventilatory catheter for oxygen supply in advance,the oxygen flow was set at 2 to 4 L/rmin according to the patients' condition,then the airway stenting was performed,after release of the stent,the ventilatory catheter was removed smoothly.Data on technical success,clinical outcome and follow-up were collected and analyzed respectively.The paired t test was performed to compare variables before and after tracheal stenting.Results Ventilatory catheter-assisted airway stenting under local anesthesia was technically successful in all patients.A total of 25 stents were placed in 25 patients.The stents included I-shaped stents (n=19) and Y-shaped stents (n=6).After the oxygen supply,the patients' SaO2 was increased to 94％ to 97％ rapidly.When the stent introducer sheaths were passing through the stenotic site,the SaO2 could be maintained at 92％ to 97％.The improvement of the respiratory difficulty was achieved in 100％ of our patients.The hypoxia symptom was relieved immediately after stents placement,the dyspnea score decreased to grade 0 in 2 patients,to grade Ⅰ in 19 patients and to grade Ⅱ in 4 patients.Respiratory rate and SaO2 improved from (30.0±2.1) times/min and (6.0±3.8)％ before stenting to (19.7±1.6) times/min (t=23.33,P＜0.01) and (93.0± 1.7)％ (t=23.50,P＜0.01) after stenting,respectively.Through the follow-up,3 patients suffered the stent-related complications after discharge,the complications included re-stenosis (n=2) and fracture(n=1).Conclusion Ventilatory catheter-assisted airway stenting under local anesthesia can be an effective,simple and safe method for airway stenosis.

Objective To evaluate the therapeutic results of comprehensive interventional therapy for antiphospholipid syndrome (APS) complicated by deep vein thrombosis (DVT). Methods A total of 10 patients with APS complicated by DVT, who were encountered at authors’ hospital during the period from January 2001 to October 2013, were enrolled in this study. The patients included 3 males and 7 females with a mean age of 45 years (39-74 years). The patients were divided into pure anticoagulantion therapy (group A, n = 4) and catheter-based thrombolysis via the jugular vein combined with anticoagulantion therapy (group B, n = 6). The clinical data were retrospectively analyzed. After the treatment warfarin was orally administered in all patients for at least one year. Results There were no significant differences in general clinical characteristics between the two groups. Before the treatment, the circumference difference of the thighs was (5.55 ± 0.51) cm in group A and was (5.13 ± 0.45) cm in group B. After the treatment, the circumference difference of the thighs was (1.85 ± 0.31) cm in group A and was (0.95 ± 0.26) cm in group B. In both groups, the postoperative calf size was significantly reduced when compared with the preoperative one (both P < 0.01), which was more obvious in group B than in group A (P < 0.05). The detumescence rate in group B was significantly higher than that in group A, which was (81.7 ± 4.1)% vs (67.3 ± 3.6)%(P <0.01). The average hospitalization days of group B and group A were (13.83 ± 0.75) days and (20.75 ± 2.63) days respectively, and the difference was statistically significant (P < 0.05). In group A, clinical effective result was obtained in three patients and ineffective result in one patient, while in group B clinical cure was obtained in all patients. Conclusion In treating APS complicated by DVT, catheter-based thrombolysis via the jugular vein combined with anticoagulantion therapy is safe, effective and time-saving, while pure anticoagulation therapy has only limited efficacy.

Objective:To evaluate the assistant role of manifestations under tracheoscopy in the diagnosis of invasive pulmonary aspergillosis (IPA) in severe patients.Methods:A retrospective study was conducted. The patients with suspected IPA admitted to intensive care unit (ICU) of Affiliated Hospital of Binzhou Medical College from January 2015 to December 2019 were enrolled. The diagnosis, clinical diagnosis and suspected diagnosis were made according to the grading criteria of Guidelines for the diagnosis and treatment of invasive fungal infection in severe patients (2007). Those who met the criteria were enrolled in the IPA group, and those who did not meet the criteria or other pathogens were enrolled in the non-IPA group. The general data of the patients were collected, and the changes of tracheal and bronchial mucosa under tracheal microscope before and after treatment were recorded, as well as the results of galactomannan (GM) test and aetiology culture of bronchoalveolar lavage fluid (BALF). The baseline, bronchoscopy and pulmonary CT manifestations and their dynamic changes were compared in each group. Results:A total of 142 patients with suspected IPA were finally enrolled. Among them, 12 were pathologically proven IPA, 77 were probable IPA, 22 were possible IPA, and 31 were undefined IPA. Of the 142 patients, 60 had typical manifestations of mucosal injury under bronchoscopy, including 7 proven IPA patients (58.3%), 52 probable IPA patients (67.5%), and 1 possible IPA patient (4.5%), but none undefined IPA patient. The patients undergoing lung CT scan were 12 proven IPA patients (100%), 73 probable IPA patients (94.8%), and 21 possible IPA patients (95.5%), respectively. Most of the Chest CT showed patchy or strip density increasing and other non-specific manifestations. There were 3 proven IPA patients (25.0%), 7 probable IPA patients (9.0%), and 0 possible IPA patient (0%) who had typical IPA CT manifestations (halo sign and cavity or crescent sign). Among the patients of proven IPA and probable IPA (89 cases), there were a total of 35 cases with endoscopic airway mucosal injury and tracheoscopy reexamination ≥ 3 times. All the 35 patients received anti-aspergillus treatment, among which 16 survived and 19 died. Among the 16 patients who survived, the microscopic appearance of mucosal injury was gradually reduced and the clinical manifestations were gradually improved. Of the 19 patients who died, 16 had deteriorated endoscopic airway mucosal injury.Conclusions:The specific manifestations of severe patients with bronchial mucosal injury are of great significance in the diagnosis of IPA. In the case of severe patients who cannot receive pathological examination or chest CT in time, dynamic observation of the changes of airway mucosal injury is a simple auxiliary method to discover the changes of patients' condition in time, evaluate the effect of antifungal therapy and the prognosis of IPA.
