Objective To survey the application of diagnosis and implementation of treatment guidelines of cerebrovascular disease( CAD)combined community acquired pneumonia( CAP)in the community of Shenyang. Methods Randomly chose 7 hospitals in different levels in districts and counties of Shenyang,and made a retrospective survey on the treatments of CAD combined CAP from Oct. 2009 to Jun. 2012 to clear the implementation. Meanwhile,the collected cases were divided into in compliance with guidelines group and non compliance with guidelines group. The information including clinical stable time,length of hospital stay,efficient treatment,empiric therapy and prognosis with the help of guidelines were collected. Results Four hundred and eighty-eight cases were qualified from collected 532 cases,in which,38. 5% initial diagnosis and treatment was accord with the guidelines formulated by the Respiratory Branch of Chinese Medical Association. The efficiency of initial empirical treatment was 84. 5%. The clinical stable time in compliance with guidelines group was (5. 00 ± 0. 27)d,better than that in non compliance with guidelines group((8. 00 ± 0. 45)d;P=0. 021). The length of hospital stay was(11. 00 ± 0. 25)d in compliance with guidelines group,significantly less than that in non compliance with guidelines group(( 14. 00 ± 0. 53 ) d;P =0. 015 ). The effective rate of patients with respiratory failure in compliance with guidelines group was 90. 9%,higher than non compliance with guidelines group(58. 6%),and the difference was significant(P=0. 026),while there were no significant differences in terms of gender,heart and lung diseases. Conclusion There is the smaller patient proportion that diagnosed and cured in accordance with the guidelines formulated by the Respiratory Branch of Chinese Medical Association. It is no distinctive difference for the efficient treatment of guidelines. But selected antibiotic application according to the guidelines can improve the clinical stable time and hospital stay of CAD combined CAP,as well as reduce invalid cases and reduce the mortality rate. The guidelines need to be further extended.

The effect of intravesical formalin instillation as a therapeutic modality for intractable bladder hemorrhage in well known. And despite clear evidence of therapeutic efficacy of intravesical cytotoxic drugs and / or BCG immunotherapy, there have been substantial recurrences during follow up after transurethral resection for superficial bladder tumor. If formalin injected at the bed of superficial bladder tumor is able to coagulate and necrotize the tumor, it will be greatly helpful to the patients with recurrent bladder tumor developed during follow up. Since this technique is applicable on outpatient basis, an economical as well as a psychological burden of the patients can be reduced considerably. The purpose of this study is to evaluate the effect of submucosal formalin injection on rat bladder wall. 36 healthy adult male Sprague-Dawley rats (weighing 350 gm in average) were divided into 3 groups: In Group I (control group), 0.01ml of normal saline was injected submucosally at the left posterolateral wall of the bladder opened under intraperitoneal Nembutal anesthesia; In Group II and III, 0.01 ml of 10% and 4% formalin, respectively, were administered at the same site as in the Group I, two rats in each group were sacrificed at day 1, 2, and 3, and week 1, 2, and 4 after injection, respectively. Gross and microscopic examination of the cystectomized specimen were done in each group. In the Group II, bladder stones were formed at week 1, and in both the Group I and III, stones were seen at week 2 post injection. There was no significant difference in histologic findings of the bladder between the group II and III. Mucosal ulcer and/or prominent mucosal disruption was observed at 24 hours after injection in both Group II and III. Epithelial regeneration began at day 2, and was marked at day 3, and epithelial lining was almost normalized one week after injection. Subepithelial edema, telangiectasia and inflammatory reaction were prominent at 24 hours post formalin injection. Subepithelial edema persisted in moderate degree for 1 week. Telangiectasia and inflammatory reaction were noted for 4 weeks. Mild degree of these findings also appeared in the control group. Fibroblastic proliferation appeared at day 2 and persisted in moderate degree for 4 weeks. There has been no mortality or bladder perforation. These results suggest that clinical application of this technique is feasible for the selected cases of recurrent, solitary superficial bladder tumor. However, optimal dosage of formalin in relation to the size of the lesion remains to be investigated.

[Objective]To examine the mechanism and clinical outcome of the traction reduction method in treating the adult shoulder dislocation.[Method]From January 1997 to August 2007,68 patients diagnosed with shoulder-dislocation received reduction with this method.A retrospective and observational study of the outcomes was assessed in a number of patients.There were altogether 68 patients,51 male and 17 female,with an average age of 49(ranging from 16-82 years old).Forty of the cases occurred in the right shoulder and 28 others in the left,all caused by trauma:15 in traffic accidents,32 by injuries from falls,and 21 by sports injuries.Forty of the dislocations lied under the processus coracoideus,17 under the glenoid,6 under the collar bone and 5 post dislocation.Seventeen of the patients had recurrent dislocation,13 with nodules avulsion fracture of the humerus,2 with brachial plexus injury,3 with surgical neck of humerus fractures.The shortest time of restoration after injury was 30 minutes,and the longest 10 days,with an average of 2.1 days.[Result]Patients that had received the reduction method for 30 seconds to 5 minutes were all recovered with one treatment,the result being confirmed by X-rays.Sixty-four of the patients were followed up for 6-24 months and the clinical results were:61 cured and 3 turned to the better.[Conclusion]This method is easy and flexible in the reduction of adult shoulder dislocation,with fewer complications than other traditional methods.It accords with the shoulder anatomy and principles of bio-mechanics,and it is suitable to popularizing.

Objective To study the effect of Shenfu injection combined with low dose glucocorticoid on endothelial function and blood coagulation in elderly patients with severe pneumonia. Methods 120 patients with severe pneumonia in our hospital from January 2014 to January 2017 were selected,and randomly divided into treatment group and control group,60 cases in each groups.. All patients were treated with conventional treatment. On this basis, the control group was treated with small dose of glucocorticoid. The treatment group was treated with Shenfu Injection on the basis of the control group. The severity, endothelial function and coagulation function of the two groups were compared at different times after treatment. Results The scores of APACHE and 120 h in the two groups were significantly lower than those in the control group (P<0.05). The score of the treatment group was lower (P<0.05) than that of the control group (96 h). After treatment, the two groups of patients with s E-selectin, V WF, APTT, D-D were significantly decreased, PLT significantly increased, significant difference (P<0.05); compared with the control group, s E-selectin, V WF, APTT, D-D and other indicators of the treatment group decreased and PLT increased even more sharply, there is statistical significance (P<0.05). Conclusion Shenfu injection combined with small dose of glucocorticoid therapy, can alleviate the function and coagulation function in patients with endothelial damage, relieve endothelial dysfunction, improve coagulation status of patients, and has higher application value.

Objective To analyze the clinical effect of nutritional support for postoperative patients with esophageal cancer with fat emulsion and amino acids (17) and glucose (11%) injection (Calvin injection). Methods A total of 68 patients with esophageal cancer treated in the chest surgery in our hospital from December 2014 to December 2016 were selected and randomly divided into two groups with 34 cases in each group. All patients were treated with surgery for esophageal cancer. The patients in the study group were treated with Calvin injection after operation while patients in the control group were treated with conventional fluid replacement therapy. Subjective comprehensive assessment (SGA) was used to assess the nutritional status of the patients and the weight, serum total protein (TSP), serum albumin (Alb), transferrin (TF) content, urea nitrogen content in on one week, malnutrition improvement and complications of the patients in two groups were recorded and compared. Results The weight of the patients with esophageal cancer in the two groups after operation was decreased, and the weight loss of the patients in the study group was lower than that of the control group and the difference was statistically significant (P<0.01). The decrease degree of TSP, Alb and TF in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). The negative nitrogen balance of the two groups was improved, and the improvement of the negative nitrogen balance in the study group was better than that in the control group, and the difference was statistically significant (P<0.01). The postoperative malnutrition in the patients with esophageal cancer was improved. The improvement degree of malnutrition in the study group was better than that in the control group, and the difference was statistically significant (P<0.05). The incidence of complications in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared with the traditional method of postoperative fluid replacement, Calvin injection can improve the recovery of the body function of the patients with esophageal cancer after operation, improve the patient's negative nitrogen balance and nutritional status, reduce the incidence of complications, and improve the clinical prognosis. This treatment is safer and more effective and it is worth popularizing in clinical practice.
