Objective To summarize the experience in application of the bovine jugular vein valved conduct in right ventricular outflow tract (ROVT) reconstruction. Methods Totally 14 patients [6 male, (6.3?5.4) years old] underwent ROVT reconstruction from February 2004 to March 2005 was recorded, and the function of the implanted bovine jugular vein valved conduit was evaluated by Doppler echocardiography one month later after operation. Results There was no perioperative morbidity related to the bovine jugular vein valved conduit. 14 patients were discharged well. One month after operation, echocardiography showed that reconstructed ROVT was patent, and only four implanted conduits had mild regurgition. Conclusion The bovine jugular vein valved conduit provides the favorable hemodynamic performance and thus could be an excellent substitute for the homograft in the reconstruction of ROVT. The mid- and long-term outcomes required further study.

The status of marine bioresources and the marine eco-environment issues were summarized and discussed, and the strategies for the development of Chinese marine bioresources in the future were proposed. The degradation of marine eco-environment and unreasonable exploitation of the resources resulted in acute decline of Chinese marine bioresources. The feasible stratagies for the sustainable use of marine bioresources should be to intensify the basic research on marine bioresources science, to strengthen the protection of the marine environment and conservation of marine living resources, and to exploit and utilize marine bioresources scientifically and reasonably by using high-technology including marine biotechnology.

Objective To investigate effects of rectal cancer to undergo total mesorectal excision (TME)or three space dissection(TSD)with pelvic autonomic nerve preservation(PANP).Methods TME or/ and TSD was applied in 247 Patients with advanced rectal cancer in which 185 cases (74.9 %) underwent PANP(Group P)including TME-PANP(Group Pro)139 cases and TSD-PANP(Group Ps)46 cases.The other 62 cases underwent none-PANP(Group P-)due to tumor invasion.Results There were no death cases for operation inall patients.Group Pm was better than Group Ps in the operation time and the difficulty of proce- dure(P0.05).Conclusion The procedure with TME to preserve pelvic autonomic nerves adapts to the majority of rectal cancer patients.TSD procedure is more complex than TME.Statistically,the survival differ- ence between Patients with TSD and with TME is no defective.The survival time is determined to the tumor's earlier diagnosis and therapy.

OBJECTIVETo evaluate the efficacy and safety of percutaneous coronary intervention (PCI) combined cardiac resynchronization therapy (CRT) for refractory heart failure secondary to ischemic cardiomyopathy (ICM).

METHODSPCI and CRT were performed in 7 ICM patients confirmed by angiography with NYHA class IV, QRS duration >/= 130 ms in 6 of them, III degrees AVB in 1 patient, fast ventricular heart rate Af in 1 patient, ventricular fibrillation history in 2 patient. All of them had their LVEDD >/= 55 mm, and LVEF

RESULTSThe procedures of PCI and CRT were performed successfully in all patients. Five patients received right atrial and biventricular pacing, one patient with Af received biventricular pacing and atrial-ventricular node radiofrequency ablation at the same procedure, and the another one patient received CRTD. One out of seven patients died of re-AMI 4 months after the combination therapy, and the other 6 patients had been alive 5 - 41 (23.2 +/- 13.8) months during the follow-up period. The heart function of the 7 patients had further improved after PCI and CRT combined therapy compared to that of PCI or CRT only. Their NYHA class decreased from IV to II, 6-minute walking distance increased steadily, and mitral regurgitation reduced and QRS duration shortened significantly. The LVEDD decreased and LVEF increased significantly in 2 patients without ventricular aneurysm, and slight improvement or no change were in the other 5 patients.

CONCLUSIONFor patients with refractory heart failure secondary to ICM, the combination of PCI and CRT could obviously improve their heart function, quality of life and prognosis, which also very safe in perforation.

Objective The purpose of this study was to analyze the anatomy variation of coronary vein system in patients with ischemic heart disease (IHD) and non-ischemic heart disease (NIHD).Method Forty-one patients with IHD and 87 patients with NIHD [101 men, mean age (63.5 ± 10. 6)years] were included in this study. Results Coronary sinuses were successfully cannulated and venographies were obtained in 127 cases. Transvenous LV pacing leads were successfully placed in optimal coronary vein in 123 cases (96. 09% ). The majority (76. 38% ) patients had at least one or more vessel abnormalities (thinness, stenosis, tortuousity, lack of lateral marginal vein or postero-lateral vein). The incidence of thin and tortuousity was significantly higher in lateral marginal vein than that in postero-lateral vein (P <0. 05 -0. 01 ). The incidence of lack of postern-lateral marginal vein was more frequent than the lack of lateral vein (P < 0. 05 ). The rate of abnormality in both vessels was 25. 2%. Incidence of vein lack in male was more frequent than in female ( P < 0. 05 ). The thin and tortuousity of vessels in female were more frequent than in male ( P < 0. 05 ) . The incidence of thin and tortuousity of postero-lateral and abnormality of both vessels was significantly higher in IHD than in NIHD patients ( P < 0. 05 ). All coronary sinus myocardial bridges occurred in NIHD. Stenoses of left anterior descending (LAD) and left circumflex (LCX) were mostly associated with abnormality of lateral vessels. Conclusions The anatomic variations of lateral and postern-lateral coronary vein were more frequent in this patient cohort. Vein lack in male was more frequent and the thin and tortuousity of vessels were less in male than in female patients. The ratio of vessel abnormality is higher in patients with IHD. Coronary arteries stenosis and position of infarction are associated with anatomic variations of coronary vein system.

In order to find the optimal topographical factor for regionslization, the content of cimetidine in 116 Sinopodophyllum hexandrum sample collected from Sichuan, Qinghai, Gansu, Tibet, Yunnan and Shaanxi provinces, was determined. Using mathematical statistics and geographical spatial analysis of GIS analysis, the relationship between content of podophyllotoxin and influencing factors including altitude gradient and gradient position was analyzed. It is found that the optimal altitude was 2 800 m to 3 600 m, the aspect of slope north or northeast and northwest and the slope 12 degrees to 65 degrees with a high suitability degree. Considering the artificial planting, the suitable planting area for S. hexandrum is comfirmed. The topographical factor is important for S. hexandrum regionalization, but has hardly effect on podophyllotoxin content. The results of the study provide an important scientific basis for S. hexandrum production development. But there are many factors which affect suitability index and podophyllotoxin content of S. hexandrum, it is necessary to consider other factors like climate and soil while exploitation and protection of S. hexandrum.

This paper summarizes the Chinese medicine diagnosis and treatment experience of Professor Wang Shuchuan,the first session national famous Chinese medicine practitioner,on paediatric Mycoplasma pneumoniae pneumonia.It concludes that the main e-tiology and mechanism of paediatric Mycoplasma pneumoniae pneumonia is wind-warmth attacking the lungs,phlegm-heat stagnation,and injury of both qi and yin.During the initial phase,there is an invasion of the lung by dryness and warm winds,with lung depres-sion and loss of dispersion being the priority;the progression phase is mainly characterized by heat stagnation and phlegm coagulation,with phlegm heat blocking the lungs;the recovery phase is characterized by qi depletion and damage to the yin,along with yin deficien-cy and the pathogenic qi lingering internally.Accordingly,the treatment of Mycoplasma pneumoniae pneumonia is divided into three stages according to its main symptom of cough.The initial cough phase focuses on dispersing the lung and moistening the dryness with pungent-cool;the phlegm cough stage pays attention to clear the heat and purge the phlegm;the deficiency cough stage focuses on benefiting the qi and nourishing the yin and reinforcing the healthy qi,which has achieved satisfactory clinical efficacy.

OBJECTIVETo summarize the etiology and treatment of gynecomastia in male children.

METHODSThe clinical data of 38 boys with gynecomastia at ages of 2-14 years were retrospectively studied.

RESULTSIn the 38 cases, 17 cases were identified as adolescent breast hyperplasia, 2 cases were relevant to primary disease, 4 cases were caused by ingestion of drugs containing hormone, and 15 cases did not show identifiable causes and were diagnosed as idiopathic gynecomastia. For the 3 children with breast development in B3 stage, oral rupixiao was administered (1.34 g, tid) for one month. For 16 children at ages of over 12 years with breast development in B2 stage and with obvious clinical symptoms, oral rupixiao was administered (1.34 g, tid) for 3-5 days. The other patients did not receive drug treatment. In a one month to one year follow-up, most of the patients recovered well.

CONCLUSIONSThe etiology of gynecomastia in male children includes adolescent breast hyperplasia, ingestion of drugs containing hormone and secondary causes. Most gynecomastia can be attributed to physiological reasons. Only a few children with obvious clinical symptoms need drug treatment.

OBJECTIVETo evaluate the feasibility and efficacy of enteral nutrition (EN) in patients underwent open-abdomen managements.

METHODSTwenty-one patients who received at least 3 days of EN after opening the peritoneal cavity between January 2003 and November 2006 were included in this study. Energy expenditure and actual caloric and protein intake were determined in some patients. The levels of serum protein and nitrogen balance before and after the EN were analyzed. Other related complications were also evaluated.

RESULTSAverage daily total caloric intake was 93% - 95% of estimated needs. The EN support was administered (8.8 +/- 5.5) d after opening the abdominal cavity and lasted for (51.5 +/- 33.6) d. Initial serum protein levels were low and below normal but increased in all of the patients after the EN. The average nitrogen balance was (-28.6 +/- 5.4) g/d. Diarrhea, gastric reflux, vomiting and abdominal distention occurred in 67%, 23%, 9.5% and 23% of the patients, respectively. All the complications were managed well.

CONCLUSIONSEN support could be effectively and safely given in patients requiring opening peritoneal cavity management.
