Objective To explore the application effect of strengthened pulmonary rehabilitation exercise in lung cancer patients with severe pulmonary ventilation dysfunction during perioperative period. Methods A total of 96 patients receiving lung cancer radical treatment under thoracoscope in our hospital during March 2013 to April 2015 were collected, and for all these patients, pulmonary function test before treatment showed that there was severe pulmonary ventilation dysfunction. The patients were divided into the routine group and the intervention group by random digital table method, with 48 patients in each group;patients in the routine group received routine perioperative nursing, and those in the intervention group received the strengthened pulmonary rehabilitation intervention plan; change in pulmonary function before treatment, duration of mechanical ventilation, time of oxygen therapy, retaining time of chest tube, length of hospital stay and occurrence of complications after treatment were compared between the two groups. Results After strengthened pulmonary rehabilitation intervention in the intervention group, the FVC was (2.63±0.47) L, the MVV was(53.14±9.40) L, the DLCO was(19.26±2.63) ml·min-1·mmHg-1, the VO2 was (23.15±4.36) ml/kg and the O2Pulse was(10.98±2.52) ml·min-1·times-1, Which were significantly improved compared with those before treatment, (2.41±0.40) L,(46.98±8.91) L,(17.56±2.83) ml·min -1·mmHg -1, (20.17±4.35)ml/kg and(9.82±2.07) ml·min-1·times-1, t=2.521, 3.512, 3.112, 3.421, 2.515, P<0.01 or 0.05. While there was no obvious change in the above- mentioned indexes of those in the routine group. After treatment of patients in the intervention group the duration of mechanical ventilation was (9.42±3.17) hours, time of oxygen therapy was (76.23±21.18) hours, retaining time of chest tube was (3.58±1.44) days and length of hospital stay was (6.62±2.14) days, which were significantly shorter than those in the routine group, (17.29±4.79) hours,(92.14±24.29) hours, (4.73±2.15) days and(8.68±2.96) days. The occurrence rates of complications such as pulmonary infection, pulmonary atelectasis and respiratory failure were 12.50%(6/48),10.42%(5/48) and 4.17%(2/48)in the intervention group, significantly lower than those in the routine group, 41.67%(20/48),29.17%(14/48) and 18.75%(9/48), χ2=10.338, 5.315, 5.031, P <0.01 or 0.05. Conclusions Strengthened pulmonary rehabilitation intervention can improve pulmonary function of lung cancer patients with severe pulmonary ventilation dysfunction before treatment, reduce the occurrence rate of post- operative complications and enhance safety during the perioperative period; it is worth of being further promoted clinically.

Objective To prepare the small intestinal submucosa (SIS) to be used as a scaffold in constructing engineered cardiac tissue. Methods Small intestinal submucosa of pig was treated with 0.25% trypsin and then 0.5% SDS for 24 hours each to obtain decellularized SIS. The obtained SIS was tested for its mechanical strength by stretching both horizontally and longitudinally with a material test machine. The cytotoxicity and histocompatibility of the material was also examined. Then the cardiomyocytes harvested from 3-day old neonatal rats were seeded on the SIS to construct engineered cardiac tissue sheets. These acquired engineered cardiac tissue sheets were immunohistochemically stained and observed with inversion microscope and transmission electromicroscope to evaluate their characteristics. Results SIS was decellularized completely. The mechanical capability of the decellularized SIS was satisfactory. Under 15% stretching, its strain and stress was nearly linear. SIS showed no cytotoxicity and inflammatory response. After 12 hours, the cardiomyocytes seeded in the SIS scaffold began to beat spontaneously. Two days later, the cardiomyocytes-SIS scaffold composite (engineered cardiac tissue sheet) began to beat spontaneously, and could beat spontaneously for 14 days. The constructed engineered cardiac tissue sheets consisted of layers of cardiomyocytes and with abundant extracellular collagen in the sheet. Conclusions SIS with good mechanical capability and biocompatibility has been prepared successfully, and then the engineered cardiac tissue has been constructed successfully based on the SIS scaffold.

The debitterizing effect of ternary complexes was appraised and characterization of ternary complexes was made by infrared spectrum (IR) and differential scanning calorimetry (DSC). The ternary complexes (β-CD/BH/WPI90) of berberine hydrochloride (BH),β-cyclodextrin)β-CD (and whey protein isolate (WPI90) were prepared with adopting coprecipitation preparation. The results showed that the ternary complexesβ-CD/BH/WPI90 can sig-nificantly reduced the bitterness of BH. The content of BH in the ternary complexes was 3.20%. It was concluded that the ternary complexesβ-CD/BH/WPI90 had significant effect in reducing the bitterness of BH. IR and DSC of the ternary complexesβ-CD/BH/WPI90 were different from the simple physical mixture.

Objective To prospectively evaluate the value of diffusion-weighted imaging with background signal suppression (DWIBS) in the detection and diagnoses of metastatic cervical lymph nodes. Methods Twenty patients with head and neck squamous cell carcinomas underwent conventional MRI and DWIBS. The ADC values were measured and compared between metastatic and benign lymph nodes. The abilities of DWIBS and conventional MRI in the evaluation of metastatic cervical lymph nodes were compared. Results Conventional MRI demonstrated 101 lymph nodes, in which 58 were diagnosed as metastatic nodes. When MRI criteria were used for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity, accuracy, positive and negative predictive value were 78% (47/60), 81%(44/54), 80% (91/114), 82% (47/57) and 77% (44/57), respectively. The mean ADC values of metastatic nodes (n =60) and benign nodes (n =54) were (0.945 ±0.122) × 10-3 mm2/s and (1. 210 ±0. 151 ) × 10-3 mm2/s ( t = - 10. 354 ,P ＜0. 01 ). When an ADC value of 1. 090 × 10 -3 mm2/s was used as the threshold for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity,accuracy, positive and negative predictive value were 88% (53/60), 80% (43/54), 84% (96/114), 83%(53/64) and 86% (43/50), respectively. Conclusion DWIBS is helpful in diagnosing metastatic cervical lymph nodes of head and neck squamous cell carcinoma, and is superior to conventional MRI in their detection.

BACKGROUND:Peripheral nerve defect due to limb dysfunction has always been the difficulty faced by the medical profession. Ideal materials and processing technology for constructing a tissue engineering scaffold targeting peripheral nerve repair are stil in research stage. OBJECTIVE:To review the research progress in peripheral nerve repair using col agen/silk fibroin nerve conduits. METHODS:In this paper, the first author retrieved the PubMed and CNKI from 2003 to 2016 to search articles regarding methods of constructing artificial nerve scaffolds and selection of raw materials. Data from these articles were col ected, summarized and analyzed. RESULTS AND CONCLUSION:Forty-six articles were included for final analysis. Col agen and its degradation products trigger no inflammatory response in the host because of high biocompatibility and biodegradability. However, its use is largely limited by its rapid degradation and poor physical performance. Silk fibroin has a high flexibility and biocompatibility, and exhibits a slow degradation in vivo. As a rapid prototyping technique, three-dimensional printing can print various forms of scaffolds within a short time, characterized as high-quality pore structure and large-scale production. Given these, the col agen/silk fibroin nerve conduit prepared using the three-dimensional printing technology can maintain the biocompatibility and even improve the mechanical properties of the raw materials. Until now, more investigations on nerve repair using col agen or silk fibroin have been done, and we have never stopped improving the production process of these scaffolds. Therefore, the col agen/silk fibroin scaffold prepared using the three-dimensional printing technology is expected to become the main candidate for the repair of peripheral nerve defects.
