| 1 | 中国珠江三角洲地区复合基-塘系统的新进展:生态学意义显示文摘珠江三角洲地区的基-塘农-渔业生产形式已经有数百年的历史,但现在那里的环境正在发生着急剧变化。经济改革之后,环境的严重退化已经使农-渔业生产结构、空间格局和农业生物品种发生了很大改变,特别是在顺德市和南海市。80年代后期,池塘饲养的传统家鱼养殖数量的下降,出现了更为复杂的、集约化的单一品种的养殖。面向市场的、经济价值较高的单一品种养殖系统,主要是通过扩大池塘面积,来增加产值,以牺牲生态效益为代价促进了经济的发展。本研究考察了1984~1994年基-塘面积比率的变化,并提出了关于新型的单一养殖系统的可持续性问题。 | Amy Wong Chor Yee 闵庆文 | 1999 | AMBIO-人类环境杂志1999，28，6： | 8 |
| 2 | Testicular sperm extraction and intracytoplasmic sperm injection in non obstructive azoospermia显示文摘Objective To report the experience in sperm extraction from testicular biopsies (TESE) performed from March 1996 to July 1998 in men with non obstructive azoospermia (NOA) Methods Comparisons of age, volume of both testes, serum FSH and testosterone in men, and histology of testicular samples in the first cycles between cycles with spermatozoa found and those without spermatozoa found were performed Comparisons of fertilization, cleavage and pregnancy rates between cycles with spermatozoa injected and those with spermatids injected were performed Results Spermatozoa were found in only 12 out of 26 first TESE cycles (46 2%) and other cycles had spermatids (round cells) only Age of men, history of mumps orchitis/oligozoospermia, volume of both testes and serum FSH/testosterone levels in men were not significantly different between cycles with and without spermatozoa The fertilization rate was significantly higher in cycles with spermatozoa injected than those with round cell injections (63 3% vs 23 2%, P <0 0001, Chi squared test) The pregnancy rate was 14 3% per cycle when spermatozoa were injected Conclusions TESE followed by Intracytoplasmic sperm injection (ICSI) is an effective treatment in patients with NOA Less than half of the patients undergoing TESE had spermatozoa recovered Age of men, volume of both testes and serum FSH/ testosterone levels in men were not useful in predicting successful recovery Compared to using ejaculated and epididymal spermatozoa, fertilization and pregnancy rates were achieved when testicular spermatozoa were used for | Ng Hung Yu Ernest, Lau Yee Lan, Yeung Shu Biu, So Wai Ki, Tam Po Chor and Ho Pak Chung | 2000 | Chinese Medical Journal2000，，3： | 7 |
| 3 | Unexpected complication of arteriovenous fistula of the left common carotid to internal jugular vein following central venous catheterization显示文摘Incidence of inadvertent arterial puncture secondary to central venous catheter insertion is not common with an arterial puncture rate of<1%.This is due to the advancements and wide availability of ultrasound to guide its insertion.Formation of arteriovenous fistula after arterial puncture is an unexpected complication.Till date,only five cases(including this case)of acquired arteriovenous fistula formation has been described due to inadvertent common carotid puncture.The present case is a 26-year-old man sustained traumatic brain injuries,chest injuries and multiple bony fractures.During resuscitative phase,attempts at left central venous catheter via left internal jugular vein under ultrasound guidance resulted in inadvertent puncture into the left common carotid artery.Surgical neck exploration revealed that the catheter had punctured through the left internal jugular vein into the common carotid artery with formation of arteriovenous fistula.The catheter was removed successfully and common carotid artery was repaired.Postoperatively,the patient recovered and clinic visits revealed no neurological deficits.From our literature review,the safest method for removal is via endovascular and open surgical removal.The pull/push technique(direct removal with compression)is not recommended due to the high risk for stroke,bleeding and hematoma formation. | Tan Chor Lip Henry Tan Jih Huei Mohamad Yuzaidi Lenny Suryani Safri K.Krishna Imran Alwi Rizal Md Idris Mohamad Azim Hanafiah Harunarashid | 2020 | Chinese Journal of Traumatology2020，23，1： | 5 |
| 4 | Risk factors and natural history of breast cancer in younger Chinese women显示文摘AIM: To investigate the age differences in the risk factors, clinicopathological characteristics and patterns of treatment of female breast cancer patients. METHODS: Seven thousand one hundred and fiftytwo women with primary breast cancer from the Hong Kong Breast Cancer Registry were recruited after receiving patients' consent, they were asked to complete standardized questionnaires which captured their sociodemographic characteristics and risk factors associated with breast cancer development. Among them, clinicopathological data and patterns of treatment were further collected from medical records of 5523 patients with invasive breast cancers. Patients were divided into two groups according to the age at diagnosis: younger(< 40 years old) vs older patients(≥ 40 years old) for subsequent analyses.RESULTS: Analysis on the sociodemographic characteristics and exposure to risk factors were performed on 7152 women with primary breast cancer and the results revealed that younger patients were more likely to have unhealthy lifestyles; these include a lack of exercise(85.4% vs 73.2%, P < 0.001), having high stress in life(46.1% vs 35.5%, P < 0.001), having dairy/meat-rich diets(20.2% vs 12.9%, P < 0.001),having alcohol drinking habit(7.7% vs 5.2%, P = 0.002). Younger patients were also more likely to have hormone-related risk factors including nulliparity(43.3% vs 17.8%, P < 0.001) and an early age at menarche(20.7% vs 13.2%, P < 0.001). Analyses on clinicopathological characteristics and patterns of treatment were performed on 5523 women diagnosed with invasive breast cancer. The invasive tumours in younger patients showed more aggressive pathological features such as having a higher percentage of grade 3 histology(45.7% vs 36.5%, P < 0.001), having a higher proportion of tumours with lymphovascular invasion(39.6% vs 33.2%, P = 0.003), and having multifocal disease(15.7% vs 10.3%, P < 0.001); they received different patterns of treatment than their older counterparts.CONCLUSION: Younger patients in Hong Kong are more likely to encounter risk factors associated with breast cancer development and have more aggressive tumours than their older counterparts. | Winnie Yeo Hang-Mei Lee Amy Chan Emily YY Chan Miranda CM Chan Keeng-Wai Chan Sharon WW Chan Foon-Yiu Cheung Polly SY Cheung Peter HK Choi Josette SY Chor William WL Foo Wing-Hong Kwan Stephen CK Law Lawrence PK Li Janice WH Tsang Yuk Tung Lorna LS Wong Ting-Ting Wong Chun-Chung Yau Tsz-Kok Yau Benny CY Zee | 2014 | World Journal of Clinical Oncology2014，5，5： | 4 |
| 5 | Survival analysis and mortality predictors of hospitalized severe burn victims in a Malaysian burns intensive care unit显示文摘Background:Prognostic measures to determine burn mortality are essential in evaluating the severity of individual burn victims.This is an important process of triaging patients with high risk of mortality that may be nursed in the acute care setting.Malaysian burn research is lacking with only one publication identified which describes the epidemiology of burn victims.Therefore,the objective of this study was to go one step further and identify the predictors of burn mortality from a Malaysian burns intensive care unit(BICU)which may be used to triage patients at higher risk of death.Methods:This is a retrospective cohort study of all admissions to Hospital Sultan Ismail’s BICU from January 2010 till October 2015.Admission criteria were in accordance with the American Burn Association guidelines,and risk factors of interest were recorded.Data was analyzed using simple logistic regression to determine significant predictors of mortality.Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with log-rank test.Results:Through the 6-year period,393 patients were admitted with a male preponderance of 73.8%.The mean age and length of stay were 35.6(±15.72)years and 15.3(±18.91)days.There were 48 mortalities with an overall mortality rate of 12.2%.Significant risk factors identified on simple logistic regression were total body surface area(TBSA)>20%(p<0.001),inhalation injury(p<0.001)and presence of early systemic inflammatory response syndrome(SIRS)(p<0.001).Survival analysis using Kaplan-Meier survival curve showed similar results with TBSA>20%,presence of SIRS,mechanical ventilation and inhalation injury which were associated with poorer survival(p<0.001).Conclusion:The predictors of mortality identified in a Malaysian BICU were TBSA>20%,early SIRS,mechanical ventilation and inhalation injury which were associated with poorer survival outcome.The immunological response differs from individual patients and influenced by the severity of burn injury.Early SIRS on admission is an important predictor of death and may represent the severity of burn injury.Patients who required mechanical ventilation were associated with mortality and it is likely related to the severity of pulmonary insults sustained by individual patients.This data is important for outcome prognostication and mortality risk counselling in severely burned patients. | Henry Tan Chor Lip Jih Huei Tan Mathew Thomas Farrah-Hani Imran Tuan Nur’Azmah Tuan Mat | 2019 | Burns & Trauma2019，7，1： | 4 |
