BACKGROUND:Mesenchymal stem cels can differentiate into lung parenchymal cels involved in lung injury repair, providing a new approach for the application of mesenchymal stem cels in patients with chronic obstructive pulmonary disease. OBJECTIVE:To observe the effect of bone marrow mesenchymal stem cel transplantation on the repair of airway injury in rats with chronic obstructive pulmonary disease. METHODS:Twenty-four female rats were randomized into four groups: bone marrow mesenchymal stem cel transplantation group (cel transplantation group,n=12); bone marrow mesenchymal stem cels group (cel control group,n=4); model group (n=4); healthy control group (n=4). Rat models of chronic obstructive pulmonary disease were established in the cel transplantation group and model group using fumigation+lipopolysaccharide method; and at 1 day after modeling, model rats were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein in these two groups, respectively. In addition to tracheal injection of normal saline (300 μL) at 1 and 14 days, rats in the cel control and healthy control groups were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein, respectively. At 1, 7, 15 and 30 days after cel transplantation, lung tissue and serum markers of al rats were detected. RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining showed that emphysema and airway injury was milder in the cel transplantation group than the model group, but severer than the cel control and healthy control groups. (2) The total number of leukocytes and neutrophils in the peripheral blood was higher in the cel transplantation group than the cel control and healthy control groups (P < 0.05); with time, the total number of leukocytes and neutrophils was decreased gradualy. (3) Compared with the cel control and healthy control groups, the interleukin-10 level in the peripheral blood was lower and the levels of tumor necrosis factor-α and granulocyte colony-stimulating factor were higher at 1 day after cel transplantation (P < 0.05). With time, in the cel transplantation group, the interleukin-10 level was increased gradualy, the level of tumor necrosis factor-α was decreased gradualy, and the level of granulocyte colony-stimulating factor was increased first and then decreased, which was highest at 7 days after cel transplantation. (4) Partial CM-Dil-positive cels were positive for CC16. Taken together, bone marrow mesenchymal stem cel transplantationvia the tail vein can improve lung injury of rats with chronic obstructive pulmonary disease, and it is involved in the repair of airway injury through differentiation into epithelial cels and immune regulation.

Diagnostic coincidence and pendency are important statistical indexes in hospital administration,they come from hospital statistical program in hospital information system.The article discusses diagnostic coincidence and pendency in hospital information system,points out the program's fatal vices and puts forward relevant method.

Background and purpose:The prognostic role of human epidermal growth factor receptor 2 (HER-2) remains controversial in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the expression of HER-2 and its prognostic implication in patients with NSCLC.Methods:Four hundred and twenty-ifve NSCLC patients’ specimens were obtained from Zhejiang Cancer Hospital. HER-2 protein expression was determined by immunohistochemistry (IHC). The relationship between HER-2 and clinicopathological parameters and patients’ prognosis was analyzed by Chi-square test and COX proportional hazards regression model.Results:Eighty-three patients were positive expression of HER-2 (83/425, 19.5%). The expression of HER-2 was closely related with histological type (P=0.051), most patients with HER-2 positive were adenocarcinoma, then were squamous carcinoma or other histological types. However, HER-2 was not an independent prognostic indicator for the overall survival of patients with NSCLC.Conclusion:We found that the expression of HER-2 was closely connected with histological type, but it was not a predictive marker for the prognosis in patients with NSCLC.

Objective To investigate the feasibility, indications, operating technique and the clinical value of laparoscopeic surgery for ectopic pregnancy with prior history of obstetric and gynecologic operations. Methods 82 ectopic pregnancy patients with prior history of the obstetric and gynecologic operation were subjected to laparoscopic surgery. Among them, 60 patients had undergone prior obstetric and gynecologic operation only once, 21 patients had undergone twice, and the remaining one had undergone obstetric and gynecologic operation three times. The laparoscopic operation was completed in different ways as follows: puncture and injection of drug under laparoscopy, salpingectomy, resection of pregnancy in oviduct, removal of embryo through incision of oviduct under laparoscope, suction removal of embryo from oviduct, and new technique for pregnant surgery at interstitial portion. Results Of these 82 patients undergoing laparoscopic surgery, 73 cases had adhesion in different degree, and the adhesion rate was 89.0% (73/82). In the 60 patients with history of one operation, pelvic peritoneal adhesion was found in 51 patients, the adhesion rate was 85.0%. All 22 patients with two prior operations had pelvic peritoneal adhesion, and the rate was 100.0%. The laparoscopic surgery was successful in 70 cases. The rate of success was 85.4%, while in 12 patients, the operation was changed into laparectomy due to dense adhesion, and the rate was 14.6%. Of these 12 patients, in 5 of them there was endometriosis, in 6 patients chronic pelvic inflammation was found, 9 patients had a surgical history for ectopic pregnancy, 2 patients with the history of caesarean section, and one patient had a history of complicated gynecologic operation. Complications included colonic injury in one patient with ectopic pregnancy, and the operation was changed to laparotomy. Injury to the ureter happened in one patient. The operation time for laparoscopic surgery was 30-180 min. Conclusions The laparoscopic operation is an effective procedure and it has become a routine procedure for ectopic pregnancy with prior history of obstetric and gynecologic operation. Because of chronic pelvic inflammation and endometriosis, it is difficult to perform laparoscopic surgery successfully, and laparotomy should be anticipated at all time.

OBJECTIVE:To provide references for drug administrator in coping with the challenge of drug shortage and the promotion of rational drug use. METHODS: With American Society of Hospital Pharmacists Guidelines on Managing Drug Shortages as references,the feasible management strategies for drug shortage in China were put forward based on the reality of our country and our experience in the practice of drug shortage management. RESULTS & CONCLUSIONS: It is advisable to draw experiences from U.S. Food and Drug Administration to tackle the problem of the shortage of essential drugs through the co-efforts of Ministry of Public Health,State Food and Drug Administration and Stage Development and Reform Committee and develop contingency planning strategy in health care organization to deal with the shortages of certain drugs and reduce potential clinical safety hazard induced by drug shortages.
