Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed. After complete resection of the gallbladder bed, the gallbladder was pulled up to resect its neck using the Ring-shaped thread technique. The neck of the gallbladder was cut using scissor forceps. Resected gallbladder was retrieved using endoscopic net forceps via a port. RESULTS: The operation times from general anesthetizing with sevoflurane to finishing the closure of the blunt port site were about 50 min and 60 min respectively. The resection times of gallbladder bed were about 15 min and 13 min respectively without liver injury and bleeding at all. Feed were given just after next day of operation, and they had a good appetite. Two dogs are in good health now and no complications for 1 mo after endoscopic cholecystectomy using only a flexible endoscope via one port.CONCLUSION: We are sure of great feasibility of endoscopic cholecystectomy via single port for human.展开更多

Per capita occupation of grain and milk increased from 316.6 and 1 kg in 1978 to 445.7 and 26.85 kg in 2016, respectively. Per capita meat occupation also reached 61.9 kg in 2016 from nearly nothing at the beginning of the reform and opening (NBSC 1979-2018). With these successes in agricultural production, the quality of food consum ption has also improved significantly.展开更多

This qualitative phenomenological study explored the meaning and lived experiences of women, as part of larger pre-dissertation pilot on health protective sexual communication among young women in Gaborone, Botswana. This was a study conducted in two Gaborone City Council MCH clinics. Twenty women participated in individual in-depth interviews conducted in Setswana, tape-recorded, transcribed verbatim, translated into English for line by line analysis to extract themes and subthemes. Six main themes and nine subthemes emerged from the data. The main themes were: the meaning of HPSC, responsibility for HPSC, HPSC content, facilitating factors, partner’s response. Batswana women communicate with their male sexual partners about safer sex but face some difficulties. Further quantitative research can further explore women’s experiences with safer sex communication.展开更多

But earthquakes andhurricanes, floods, transportation and domestic accidents, epidemics and industrial disasters stillaccount for many thousands of deaths and injuries each year, in addition to material and socialdamage. International Standards offer widely accepted and recognized solutions to prevent andrespond to these threats. The role that standards can play in preventing or mitigating such humanand material losses is increasingly recognized and their use is rising as a consequence. 'Standardsfor a Safer World' is the theme of this year's World Standards Day to be celebrated on 14 October2005. The International Standards produced by the world' s leading international standards-settingorganizations-International Electrotechnical Commission (IEC), the International Organization forStandardization (ISO) and the International Telecommunication Union (ITU), provide a valuable safetynet.展开更多
