Objective To scrutinize the CT features of pulmonary actinomycosis and analysize the causes of misdiagnosis.Methods CT images of eleven patients with pulmonary actinomycosis proved by pathology were retrospectively reviewed.Among them,6 were scanned with additional enhanced CT scan.Results Among the 11 patients,the lesions located in the inferior lobe in 7 patients,and in the superior lobe in 4 patients.The lesions affected two or more pulmonary segments in 9 patients,6 of them involving two lobes.Irregular mass or nodules with necrotic low-attenuation areas were the main signs in all patients,and segmental consolidations were found in 6 patients.Peripherally progressive enhancement was found in all patients with contrast enhanced CT scan.Vicinity pleural thickening was found in 11 patients,while extrapleural fat deposition was found in 6 patients.One case showed erosion of the chest wall and rib.Conclusion Pulmonary actinomycosis is a chronic suppurative granulomatous inflammation,which is often misdiagnosed with neoplasm or other lung disease because of its mass-like performance.The peripherally progressive enhancement on CT has a certain diagnostic value for P\pulmonary actinomycosis.

Objective To assess voice parametric characteristics of normal children in different age?sex?and phonation conditions. Methods Voice data of 240 children were collected and analyzed with Dr. Speech software. Acoustic signal data were measured in three phonation conditions: the lowest modal voice, natural voice, the highest modal voice. Results Perturbations and normalized noise energy from the highest value to the lowest one by one were that of the lowest modal voice, natural voice, the highest modal voice. The sequences of standard deviation of fundamental frequency were that of the highest modal voice, the lowest modal voice, natural voice. Conclusion The voice quality of normal children had distinctive characteristics in different phonation conditions.

[Objective]To observe the curative effect of the Tangshen Particle on diabetes.[Methods] ICR mice were induced for diabetes by Alloxan intravenous injection,take Tangshen Particle and Xiaoke pill as the comparison group,observe each group’s glucose,lipid,renal index,urea,creatinine.[Results] The Tangshen Particle was able to decline glucose,lipid,renal index,urea,creatinine on diabetic mice,but the effect on high dose group was most obvious.[Conclusion] Tangshen Particle has good glucose-lowering and lipid-lowering effect on diabetic mice,and it has preventive and therapeutical effects on diabetic nephropathy .

Dermoid cyst is a benign cystic teratoma consisting of 3 germ cell origin tissues with predominant ectodermal origin and most commonly found in the ovary but rare in the scrotum. We reported two cases of intrascrotal dermoid cysts developed in 7 months and 3 years old boys which were confirmed hiatologically. In one case, the cyst developed from the testis and in another from the paratesticular tissue.

Objective To observe the effect of neoadjuvant chemotherapy combined with tumor cells reduction and postoperative intraperitoneal perfusion chemotherapy on the efficacy and quality of life of ovarian cancer.Methods From October 2010 to October 2013 at the Department of gynecology,Taizhou Municipal Hospital,65 cases of ovarian cancer patients for the treatment of stage Ⅲ and Ⅳ were randomly divided into intervention group (n =32) and control group (n =33).Patients in the intervention group received neoadjuvant chemotherapy after tumor cell reduction cytoreductive surgery and received postoperative intraperitoneal hyperthermic perfusion chemotherapy and conventional surgery after chemotherapy.Patients in the control group received conventional tumor cell cytoreductive surgery plus postoperative chemotherapy.Surgical status,the effectiveness of treatment,and adverse reactions were compared between two groups.Moreover,survival quality score,relapse rate,and mortality differences were compared between two groups.Results For the intervention group,operation status and effective treatment were better than the control group.The proportion of adverse reactions had no significant difference between two groups.Survival quality had no statistically significant difference between before treatment and after receiving treatment.Quality of life in the intervention group was better than that of the control group.Relapse rate,and mortality rate in the intervention group was lower than the control group.Conclusions Accepted neoadjuvant chemotherapy combined with tumor cytoreductive surgery and surgery after intraperitoneal hyperthermic perfusion chemotherapy can improve the effectiveness of treatment of ovarian cancers,and improve the quality of life,with better short-term effect.

Objective To explore the diagnosis and topical treatment of diabetic foot in patients with burns.Methods Sixty-five patients with burns complicated with diabetic foot were admitted from Jan.2002 to Dec.2006.Bacterial culture of wound excretion,peripheral nerve electromyography and vascular ultrasonography of both lower extremities were performed in a part of patients.Twenty-four patients received topical treatment,including immersion bath with hypertonic saline solution and the application of epidermal growth factor,fibroblast growth factor and complex lysozyme disinfectant.Forty-one patients underwent surgical treatment.The operation methods,surgical treatment included debridement followed by direct closure,split-thickness skin grafting,repair with local skin flap or cross leg skin flap,or amputation of foot,as determined according to the condition of the wound.Results The positive rate of bacterial culture of wound excretion was 88.7%(47/53)on admission and 30.2%(16/53)one week after topical treatment.There were abnormal findings of peripheral nerve electromyography in all 31 cases.Vascular ultrasonography revealed pathological findings in both lower extremities of all 12 patients with vascular lesion,and 9 in 16 cases without vascular lesion.The lesions in all patients except 2,who were discharged in advance,healed and the cure rate was 96.9%.Conclusion Peripheral nerve electromyography and vascular ultrasonography of both lower extremities are promising auxiliary examinations for the diagnosis of diabetic foot in patients with burns.Topical treatment,which includes immersion bath with hypertonic saline solution and the application of growth factors and complex lysozyme disinfectant,as well as appropriate surgical management,plays an important role in the wound healing.

Objective To observe the effect of low molecular weight heparin(LMWH)on hypercoagulability in extensive severe burn patients.Methods 9 patients were assigned as LMWH treatment group(TG),and another 12 burn patients with the similar extent of burn injury admitted in the same period were assigned as routine treatment group(RTG).All the treatments were the same except 5000U LMWH was given via subcutaneous injection per 12 or 6 hours to the TG group for 3-7days.The patients in normal control group(NCG)consisted of patients receiving plastic surgery.The following coagulation parameters were determined before and after the heparin treatment:prothrombin time(PT),thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),fibrinogen(Fib)and platelet(PLT).Results INR,APTT and PLT in both TG and RTG groups were significantly lower compared with that in NCG before treatment,and Fib in two former groups were higher than that in NCG.Compared with those values before treatment,Fib decreased and PLT increased significantly after LMWH treatment in TG.However,there were no significant changes in other parameters in TG after LMWH treatment.Severe side effects such as haemorrhage were not found in patients in TG.Conclusion LMWH could ameliorate hypercoagulability following severe burns.

Objective:To evaluate the possibility of prevention of Frey's syndrome by reservation and reconstruction of parotid fascia in parotidectomy.Methods:Parotidectomy with parotid fascia reservation and reconstruction was conducted in 31 cases. 12 months-12 years after operation the patients were examined by Minor test.Result:Positive reaction of Minor test was observed in 3 out of the 31 cases(9.67%).Conclusion:A parotidectomy with reservation and reconstruction of parotid fascia can efficiently prevent Frey's syndrome.

Objective:To evaluate fixation effect of intermaxillary fixation screw.Methods:63 cases with mandibular fractures were treated with open reduction,and then internal fixation were managed with intermaxillary fixation using dental arch splint or intermaxillary fixation screw randomly.The operation time,postoperation periodontal index,mouth open degree,occluding relation and fracture healing were compared.Results:There was no significant difference upon occluding relation,fracture healing and mouth open degree under two treatment methods.Compared with dental arch splint fixation method,intermaxillary fixation screw had shorter operation time and better periodontal index.Conclusion:Intermaxillary fixation screw is a good intermaxillary fixation method because of short operation time.Furthermore,it can provide enough traction retention strength and easy to maintain oral hygiene.
