Objective: To discuss the effect of Chinese materia medica on xerostomia of patients with head and neck tumor undergoing radiotherapy. Methods: 56 Cases of xerostomia of patients with head and neck tumor undergoing radiotherapy were treated with Chinese materia medica which had the effect of clearing heat and lowering pathogenic fire, nourishing yinn and promoting fluid production. I Month later, the evaluation of xerostomia was done. Results: The effective rate reached 46.4%,the improved rate was 44.6%,the total effective rate was 91.0%,and the ineffective rate was 9.0%。Conclusion: The Chinese materia medica with effect of clearing heat and lowering pathogenic fire, nourishing yinn and promoting fluid production can promote salivary secretion, relieve the dry mouth, improve the life quality.

Objective To summarize the experiences of diagnosis and treatment for blunt tracheobronchial injuries ( BTI) . Methods From January 1993 to December 2013, 15 patients were diagnosed with BTI and underwent surgical treatment at our hospital.Mean age of the 15 patients (11 men and 4 women) was 26.4 ±4.5 years.All the patients had a history of trauma, which included crushing injury in 8 cases, deceleration injury in 4, fall injury in 2, and traction-type injury in 1.BTI loca-tion: right main bronchus in eight cases, left main bronchus in four cases, upper trachea in one case, lower trachea with the right main bronchus in one case, and cervico-thoracic trachea with left main bronchus in one case .Thoracic computerized tomo-graphy was performed in 15 patients, which showed pneumothorax, subcutaneous emphysema, pneumomediastinum or falling lung sign of Kumpe.Preoperative fiberoptic bronchoscopy examination was performed in 15 cases, which included bronchial atresia in 9 cases, bronchial transection in 3 cases, laceration of trachea in 2 cases, and tracheal transection in 1 case.An e-lective surgical procedure after BTI was performed in 10 cases, and emergency surgery was performed in 5 cases.Tracheo-bron-chial laceration repair were performed in 2 cases, tracheal end-to-end reanastomosis in 1 case, and bronchial end-to-end re-anastomosis in 12 cases.Results There was no operative death, and one case was complicated with anastomotic stenosis.The average operation time was 205.7 ±41.3 minutes, and the average blood loss was 268.4 ±109 ml.The postoperative hospi-tal stay was 11.6 ±3.7 days on average.Follow-up was completed in 15 patients (mean, 29.3 months), and 15 patients were all symptomatic improvement .Conclusion The most common site of BTI was the right main bronchus near Carina parts .Al-though the diagnosis and treatment are often delayed , our findings indicate that chest CT and endoscopic findings could be used for the diagnosis of BTI.Surgical resection and reconstruction are effective methods to repair BTI successfully even many months after they occur.Often they do not require the resection of pulmonary parenchyma .

OBJECTIVE: To explore the non-neoplastic hepatic lesions in SD rats at different ages. METHODS: The specificpathogen free SD rats were collected from the blank control groups used in subacute toxicity tests,subchronic toxicity tests and chronic toxicity combined with carcinogenic tests for safety evaluation. At the end of each experiment,i. e. week 10,19,56 and 108(assigned into four groups: 10,19,56 and 108 weeks,each contained 100 rats with each sex),rats were executed. The liver organ coefficient was calculated,the pathological examination was performed,and the non-tumorous lesions in the liver were analyzed. RESULTS: The liver organ coefficients at the age of 19,56,108 weeks were lower than that of 10 weeks(P < 0. 05); those at the age of 56 and 108 weeks were lower than that of 19 weeks(P < 0. 05),and that of 108 weeks was greater than of 56 weeks(P < 0. 05). Among the 10-week-old,19-week-old,56-week-old and 108-week-old groups,the types of non-neoplastic hepatic lesions detected in the female rats were 6,6,13 and 15 respectively,meanwhile those in the male rats were 6,6,13 and 15 respectively. Both male and female rats,the incidences of hepatocyte fatty degeneration,edema and hepatic infiltration of inflammatory cells were significantly increased with the increase of age in each group(P < 0. 05). The incidences of intrahepatic bile duct proliferation and intrahepatic bile duct fibrosis in rats at the age of 56 and 108 weeks were higher than those at the age of 10 and 19 weeks(P < 0. 008).Moreover,the frequency of hepatic sinus expansion lesions in rats at the age of 108 weeks was higher than those of 19 weeks(P < 0. 008). CONCLUSION: Spontaneous non-neoplastic lesions in the liver of SD rats were common,primarily demonstrated as hepatocyte fatty degeneration,edema and infiltration of inflammatory cells. The incidences of lesions increased with the increase of age.

OBJECTIVE: To explore the spontaneous non-tumor lesion of kidney and its correlation with different age and sex in SD rats. METHODS: Eight hundred specific pathogen free SD rats were collected from the blank control groups used in subacute toxicity tests,subchronic toxicity tests and 1 or 2 years of chronic toxicity combined with carcinogenic tests. Rats were randomly divided into 4 groups with 10,19,56 or 108 weeks of experimental periods. Each group consisted of 100 female and 100 male rats. The renal tissues were collected at the end of each experiment,and the renal organ coefficients were calculated. The pathological non-tumor changes of the kidneys were analyzed. RESULTS: The renal organ coefficients in female rats at the age of 56 and 108 weeks were both lower than that of 10 and 19 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 56 weeks was lower than that of 10 and 19 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 108 weeks was higher than that of 56 weeks( P < 0. 008). The renal organ coefficient of male rats at the age of 108 weeks was higher than that of female rats of 108 weeks( P < 0. 008). The incidence of renal tubular calcium salt deposition,interstitial inflammatory cell infiltration and renal tubular dilatation in the female rats at the age of 108 weeks were higher than those in the male rats at the age of 108 weeks( P < 0. 05). The chronic progressive nephropathy incidence of female rats at the age of 108 weeks was lower than that of male rats aged 108 weeks( P < 0. 01).The renal tubular calcium salt deposition incidence of female rats aged 56 weeks was higher than that of male rats aged 56weeks( P < 0. 01). CONCLUSION: The spontaneous non-tumor lesions in the kidney of SD rats were common. The incidence of some lesions was different in the same age group with different sex.
