OBJECTIVE: Some vaginal procedures may be safer, easier and more successful if they could be done under direct sonographic vision of the object. METHODS: All the procedures were done under the guidance of transrectal sonography. Suction curettage, after using curved plastic Karman's cannula, additional curettage was done only when there was probable remaining conceptal tissue seen on sonography. If additional curettage was needed curved metal cannula made in the same form as plastic Karman's cannula is used first and then usual metal curette if the former did not work. A high frequency cautery unit was used for myolysis. Insertion of the flexible curved cautery tip into the myoma mass was done through the uterine cavity and coagulation of the myoma tissue was performed. Myoma biopsies were done with thin loop high frequency cautery tip through laparoscopy and the vagina. RESULTS: Suction curettage in 156 cases of early pregnancy and 2 cases of previous cesarean incision site pregnancy, D&C in 11 cases, chorionic villus sampling in 13 cases, polypectomy in 1 case, myolysis in 1 case and myoma biopsy in 2 cases were done. CONCLUSION: Performing some vaginal procedures under the guidance of transrectal sonography may be better.

Objective To review the primary experience of video-assisted rigid laser bronchoscopy in the treatment of tracheobronchial tumors. Methods From Sep.2002 to Nov.2004, 13 patients (15 procedures) with tracheobronchial tumors were treated with video-assisted rigid bronchoscope. Benign tumors with small pedicles were removed directly. For benign tumors with wide pedicles or tumors extending beyond the wall of air-way, total enucleating through thoracotomy were employed. In cases with malignant tumors, stenosis or obstructions were relieved by implantation of stents or cautering with electric argoulaser knife. For malignant but resectable primary tumors of trachea and main bronchi, rigid bronchoscopy might serue as a preparation of radical resection. Results Of the 5 patients with benign tumors, 4 received endoscopic total resection and 1 were conversed into thoracotomy. For the 8 malignant cases, 3 received stent implantation, 2 had palliative ablation and 3 got curative resections through thoracotomy. No peri-operative complications or death occurred in this group. Conclusion Total resection of benign tracheobronchial tumors or palliative therapy for tracheobronchial malignant stenosis or preparation of radical resection can be performed safely and efficiently by video-assisted rigid bronchoscopy.

Objective To evaluate the feasibility and safety of video-assisted rigid bronchoscopy in the treatment of benign tumors of tracheobronchus.Methods Seven patients with benign tumors of tracheobronchus were managed with video-assisted rigid bronchoscopic surgery in this hospital from September 2002 to April 2005.The endoscopic procedure was performed under general transvenous anesthesia and jet ventilation.The tumor was firstly frozen or electocoagulated for better bleeding control,and then was removed with a biopsy clamp by parts,with the pedicle treated with freezing,coagulation or argon plasma coagulation(APC).For tumors with a broad pedicle,after the bulk of tumor was ablated under bronchoscope,a conversion to open local resection was carried out.Results All the 7 operations was accomplished smoothly without mortality or severe morbidity.Except one patient with broad pedicle leiomyoma which was resected through thoracotomy after airway clean-up and intubation,all 6 patients with narrow pedicle tumors underwent a complete tumor removal endoscopically.Postoperative pathological reports confirmed the benign diagnosis as 2 cases of hamartoma,3 cases of leiomyoma,1 case of acidophilus granuloma,and 1 case of inflammation.Follow-up observations in the 7 patients for 3~36 months(mean,17.3 months) showed no recurrence.Conclusions Video-assisted rigid bronchoscopy in the treatment of benign tumors of tracheobronchus is safe and reliable.

Objective To discuss the technical strategies for thoracoscopic lobectomy.Methods Between September 2006 and May 2008,a total of 91 patients underwent thoracoscopic lobectomy in our hospital.The lobectomy and lymph node resection were completed via three mini incisions with the same procedures as those in an open surgery.Among the cases,75 had primary or metastatic malignancies,and 16 showed benign tumor.By thoracoscopy,upper right lobectomy was carried out in 21 patients,right middle lobectomy in 12,lower right in 20,upper left in 18,and lower left in 20.Results Only two cases were converted to open thoracotomy.In the other 89 patients,the mean operation time for the thoracoscopy was(185.8?52.9)minutes(ragne,60-300 minutes),and the mean blood loss was 213.2 ml(range,50-650 ml).In this series,the chest drainage lasted(6.9?2.9)days;the patients were discharged from the hospital in(9.4?3.2)days after the surgery.No severe complications or perioperative death occurred in the cases except in one patient,who developed chylothorax after the treatment.Two patients,who had primary lung cancer,showed distant metastasis at 15 and 3 months respectively after the surgery.No recurrence or metastasis was found in the other cases.Conclusions Thoracoscopic lobectomy is safe and effective for patients with indications for the surgical procedure.Surgical skills for dissection of vessels and lymph nodes are the key to the operation.

OBJECTIVE To explore the main risk factors of fungal infection in lower respiratory tract(LRT) of hospital patients,strains distribution and sensitivity to common antifungal agents so as to provide basis for earlier diagnosis and effective treatment.METHODS Retrospective analysis was taken of the 76 cases with fungal infection in LRT in patients of Taizhou Hospital from Jul 2004 to Jun 2006 based on the diagnostic criteria for nosocomial infections by Ministry of Health of PRC and also following the definition given by European Organization for Research on Treatment of Cancer(EORTC) and us Mycosis study Groap(MSG) in 2002.RESULTS Of the 76 cases,84.2% were over 60 years old.All of them had underlying diseases.Sixty cases had been repeatedly treated with 2 or 5 antibiotics before fungal infection;21 cases received glucocorticoid;6 cases had chemol and radiotherapy and 21 cases underwent invasive treatment procedures.In the three years,77 strains of fungi were isolated from all kinds of samples.Susceptibility testing indicated that the resistance to ketoconazole and miconazole was higher compared with that to fluconacole and itraconazole.CONCLUSIONS Fungal infection in LRT of hospital patients is closely related with age,long stay in hospital,wide administration of broad-spectrum antibiotics,immuno-suppressants and cytotoxic drugs.The most common fungi are Aspergillus and Mucor.There is an increasing number of strains of fungi resistant to drugs,especially to azole antifungal agents.Effective counter measures should be taken without delay.

Objective To investigate the effect of MT-1 and MT-2 in liver damage in chronic inorganic arsenate exposure mice and to explore the mechanism of arsenic-induced liver damage. Methods The male Kunming mice were randomly divided into control and exposed groups. The control group was given ordinary feed and tap water. The exposed group was given ordinary feed and 300 mg/L of sodium arsenite solution by drinking water. After 10 months of treatment, the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase(AST) and globulin (Glb) content were determined. The total RNA was extracted by the TRIzol-phenol-chlorofor-method from the liver tissue. The quantity of the RNA was determined by spectrophotometry and its purity was judged at a ratio of A260/A280. Then real-time PCR(RT-PCR) was used to measure the mRNA expression of MT-1 and MT-2. Results Compared with the control group, serum ALT, AST activity and Glb content were higher and the MT-1 and MT-2 mRNA content was lower in the exposed group (P
