Objective To observe the effects of penehyclidine hydrochloride(PHC)on lipopo-lysaccharide-induced neonatal cardiomyocyte damage.Methods After the primary cardiomyocytes culture of neonatal rat on postnatal day 1,the myocytes were randomly divided into 4 groups:the control group,the lipopolysaccharide(LPS)group,the low dosage PHC pretreatment group and high dosage PHC pretreatment group.Activities of myocardial enzymes and cardiac troponin and cell survival rate were measured.Expres-sion of NF-Κb(p65)and IκB-α(NF-κB inhibitor)phosphorylation were assessed using Western blot.Re-sults Compared with the control group,activities of myocardial enzymes and cardiac troponin in the LPS group were elevated but the survival rate were down-regulated.All these effects were reversed in the PHC pretreatment group.Results of Western blot showed that phosphorylation of IκB-αand p65 expression were up-regulated in the LPS group.In the PHC pretreatment group,phosphorylation of IκB-αand p65 expres-sion were down-regulated.Conclusion Penehyclidine hydrochloride can inhibit lipopolysaccharide-in-duced neonatal cardiomyocyte damage and the down-regulation of NF-κB activity might be involved.

Objective To explore the role of enteral nutrition in the treatment of functional delayed gastric emptying. Methods Among 15 patients with functional delayed gastric emptying after resection of esophageal or gastric cardiac carcinoma, 10 patients were treated with enteral nutrition( EN group),5 patients were treated with parenteral nutrition (PN group). Postoperative hospital stay, gastrointestinal decompression amount, recovering time of postoperative gastric emptying were observed to assess the efficacy of enteral nutrition. Results The average postoperative hospital stay was ( 14. 4 ± 4. 6) days in the EN group, whereas (20. 3 ±6. 6) days in the PN group. The average recovering time of postoperative gastric emptying was (19 ±9)days in the PN group and( 12 ± 4)days in the EN group. Conclusion The method of EN can enhance gastric emptying and is effective for functional delayed gastric emptying after resection of esophageal or gastric cardiac carcinoma

Objective To investigate the application of electronic bronchoscopy in diagnosis of recurrent tracheoe-sophageal fistula of type Ⅲ esophageal atresia. Methods 5 patients were reviewed who were suspected postopera-tive tracheoesophageal fistula recurrence of type Ⅲ esophageal atresia and examined through electronic bron-choscopy combined with injecting Methylene blue into stomach tube from Jan 2010 to Aug 2014.

Results The 5 cases were found trachea mem-brane fistula by electronic bronchoscope, recurrent tracheoesophageal fistula was diagnosed with Methylene blue in-jected into stomach tube and overflowed from trachea membrane fistula. Examination time is 3~7 minutes, the aver-age is 4.2 minutes. The 5 cases were confirmed by operation. Conclusion Electronic bronchoscopy combined with injecting Methylene blue into stomach tube to diagnose recurrent tracheoesophageal fistula is safe and feasible, the time is short and the diagnosis rate is high.

Objective To investigate the clinical effects of different doses of propranolol in treatment of infantile mixed and deep hemangioma,and to provid theoretical and experimental evidence for the treatment of hemangioma. Methods The selected 62 patients with mixed and deep hemangioma were divided randomly into low dose (1.5mg·kg-1 ·d-1 )and high dose (3.0 mg·kg-1 ·d-1 )of propranolol groups,3 times a day,6 months as a course,the changes in hemangioma size and the incidence of adverse reactions were recorded.Results The efficacy was evaluated using Achauer system.The total effective rate was 80.65% in low dose of propranolol group and 93.55% in high dose of propranolol group,including 6 cases of class Ⅰ (poor),9 cases of class Ⅱ (moderate), 11 cases of classⅢ (good),and 5 cases of class Ⅳ (excellent)in low dose propranolol group;while 2 cases of class Ⅰ (poor),4 cases of class Ⅱ (moderate),10 cases of class Ⅲ (good)and 15 cases of Ⅳ (excellent)in high dose of propranolol group.The efficacy in high dose of proprandol group was significantly better than that in low dose of proprandol group (P<0.05),there were no significant differences in the efficacies between different sites and different types (P>0.05)and there was no significant difference in the incidence of adverse reaction between two groups (P>0.05).Conclusion The efficacy of oral 3.0 mg·kg-1 ·d-1 propranolol in treatment of infantile mixed and deep hemangioma is increased significantly, and there is no significant adverse reactions after increasing doses.Therefore,high dose of propranolol should be recommended in order to improve the therapeutic effect.

OBJECTIVE: To observe the clinical and pathological features of adenoid cystic carcinoma(ACC) of external auditory canal (EAC, and analyze the possible factors related to prognosis. METHOD: One out of 8 patients with ACC of EAC underwent tumor open biopsy. 5 patients underwent the extensive tumor resection, and 2 patients underwent the modified lateral temporal bone resection (1 of the 2 subjoined a total parotidectomy). Five patients received the postoperative radiotherapy. RESULT: The time of follow up was 5-97 months. Two patients were loss to follow-up, 5 patients with disease free survival, and 1 patient survival with tumor. CONCLUSION In this study, ACC of EAC is more often observed in female. The most common clinical manifestations are otalgia and neoplasm which grows slowly. The disease has high misdiagnosis rate. Surgical treatment is effective for it.

Objective To explore the value of combined measurement of urine N-acetyl-beta-D-glucosaminidase (NAG) activity and serum Cystatin C in diagnosing diabetic nephropathy (DN) in early phase. Methods Sixty-two cases with type 2 diabetes (diabetic group) were divided into three groups according to their 24 hours urinary albumin excretion (24hUAE) : group A (normal albuminuria, 20 cases), group B (microalbuminuria, 22 cases) and group C (macroalbuminuria, 20 cases). Furthermore, 30 healthy people were involved in control group. 24hUAE,NAG,serum creatinine (SCr) and serum Cystatin C were measured, and endogenous creatinine clearance rate (Ccr) was calculated by Cockcroft-Gault formula. All these indexes among three groups were compared. Results The levels of urinary NAG activity and serum Cystafin C in diabetic group was significantly higher and Ccr was significantly lower than those in control group(P < 0.01). The levels of urinary NAG activity and serum cystatin C gradually increased in group A, B and C(P< 0.05 or < 0.01). While no significant difference was observed between group A and group B in the level of SCr (P > 0.05). There were significant positive correlations among the levels of urinary NAG activity, serum Cystatin C,24hUAE and SCr (P< 0.01),and all above showed negative correlations with Ccr (P<0.01). Co-detection of urinary NAG activity and serum Cystatin C had significantly higher positive rate [80.6%(50/62)] than single one [58.1%(36/62),61.3%(38/62)](P<0.05). Conclusion Co-detection of urinary NAG activity and serum Cystatin C may indicate early renal damage in DN, and it is valuable in diagnosing DN in early phase.
